The Japanese adverb “むしろ” is used when several judgments, options, or descriptions are compared and the speaker considers one of them to be closer to the actual situation. It is often translated as “rather,” “instead,” or “rather than A, B,” which is exactly why it is easily confused with “かえって,” another word that can also be translated as “rather” or “instead.”
For example, “高いというより、むしろ安い” does not mean that the price first became high and then low. It means the speaker is reconsidering which of the two evaluations—“expensive” or “cheap”—is more accurate. By contrast, “早く終わらせようと急いだら、かえって時間がかかった” describes an attempt to save time that actually resulted in taking longer. Both sentences might use “rather” or “instead” in English, but Japanese distinguishes whether the speaker is comparing two possible directions or describing a result that runs against the original expectation.
What Does the Japanese Adverb “むしろ” Mean? Start with the Idea of “Leaning Toward the Other Side After Comparison”
“むしろ” is an adverb used when several possible judgments or options are compared and the speaker considers one of them more appropriate. Depending on the context, it can be translated as “rather than A, B,” “more than A,” “rather,” “instead,” or “it would be more accurate to say…”.
Its most typical function is not to describe chronological change or simply create a positive-versus-negative contrast. Instead, it reallocates the focus of the sentence. For example, “先生というより、むしろ友達に近い” does not deny that the person is a teacher. It means that when describing the actual relationship, “friend” feels more accurate than “teacher.”
The alternative before “むしろ” does not always have to be stated explicitly. If someone asks “疲れたでしょう？” and the reply is “むしろ元気です,” the sentence still works. In this case, the omitted alternative is the other person’s assumption that the speaker must be tired, and the reply shifts the judgment toward “元気.” Dictionary definitions of “むしろ” likewise focus on comparing several situations and leaning toward one of them.
- Example: この店は高いというより、むしろ安いです。
Kana: このみせはたかいというより、むしろやすいです。
Translation: Rather than expensive, this store is actually quite cheap.
“高い” and “安い” are two evaluations of the same store, and “むしろ” marks the latter as the description that better matches reality. - Example: 肉より、むしろ魚のほうが好きです。
Kana: にくより、むしろさかなのほうがすきです。
Translation: I prefer fish to meat.
Meat is not completely excluded, but when the two are compared, the preference clearly leans toward fish. - Example: 疲れているどころか、むしろ元気です。
Kana: つかれているどころか、むしろげんきです。
Translation: Far from being tired, I actually feel energetic.
The first half rejects the judgment “疲れている,” while the second presents “元気” as the description that better matches the current state.
How Do You Use “むしろ”? Four Common Patterns and Positions
“むしろ” is an adverb and does not conjugate. It normally appears before the content the speaker truly wants to emphasize and can modify noun-like expressions, adjectival judgments, or an entire predicate. In actual usage, it frequently appears with “より,” “というより,” and “どころか.”
| Common Structure | Basic Meaning | Example | Nuance |
|---|---|---|---|
| Aより、むしろB | More B than A | 車よりむしろ電車が便利だ | Compares two options |
| Aというより、むしろB | Rather than A, more accurately B | 怖いというよりむしろ悲しい | Revises the original label |
| Aどころか、むしろB | Far from A, it is closer to B | 疲れるどころかむしろ元気になった | Strongly rejects A |
| Context＋むしろB | If anything, B is closer | むしろこちらのほうがいい | A is supplied by the context |
“Aより、むしろB”｜Directly Comparing Two Options or Preferences
“Aより、むしろB” is the easiest structure to understand. A and B need to belong to the same comparison category, such as transportation methods, preferences, work approaches, or scheduling choices. The speaker is not saying that A is completely wrong, but that after weighing both sides, B is preferable.
- Example: 車で行くより、むしろ電車のほうが便利です。
Kana: くるまでいくより、むしろでんしゃのほうがべんりです。
Translation: Rather than driving, taking the train is actually more convenient.
Both transportation methods are possible, but under the current conditions, the train is judged to be more suitable.
“Aというより、むしろB”｜Correcting the Previous Description to Make It More Accurate
“というより” already means “rather than A, B.” Adding “むしろ” makes B more prominent and gives the impression that “this is what is actually closer to the truth.”
- Example: この映画は怖いというより、むしろ切ないです。
Kana: このえいがはこわいというより、むしろせつないです。
Translation: Rather than scary, this movie feels more heartbreaking.
“怖い” is not necessarily completely wrong, but after watching the whole film, “切ない” better describes the lasting impression.
“Aどころか、むしろB”｜Rejecting the Original Judgment and Shifting Toward the Other Side
“どころか” already carries the meaning “far from A, the actual situation is even closer to the other side.” When combined with “むしろ,” the gap between A and B becomes even more pronounced.
- Example: この仕事は退屈どころか、むしろ毎日変化があって面白いです。
Kana: このしごとはたいくつどころか、むしろまいにちへんかがあっておもしろいです。
Translation: Far from being boring, this job changes every day and is actually interesting.
There may have been an initial impression that the job was boring, but actual experience is much closer to the opposite side.
“むしろB”｜The First Comparison Target Can Remain Implicit in the Context
In everyday conversation, A does not always need to be repeated in full. As long as the preceding conversation has already established another direction, “むしろ” can directly introduce a new judgment.
A：疲れたでしょう。
B：いや、むしろ元気になりました。
The underlying comparison is between “疲れている” and “元気になった.” Since A has already introduced the first possibility, B does not need to repeat it.
“むしろ” Does Not Only Compare Opposites: It Works Whenever Two Judgments Compete
The expressions before and after “むしろ” do not have to be dictionary antonyms. They only need to be comparable within the same judgment. “高い／安い” are direct opposites, but “先生／友達” are not. Even so, they can still be compared when describing interpersonal distance.
For example:
先生というより、むしろ相談相手に近い。
Rather than a teacher, this person is more like someone I can turn to for advice.
“先生” and “相談相手” are not opposite concepts, but the speaker is answering the same question: what kind of relationship does this person actually have with me?
So when deciding whether to use “むしろ,” there is no need to search for antonyms. Instead, look for two possible answers that are competing with each other. If B is the answer the speaker considers more appropriate, there is room for “むしろ.”
Three Common Uses of the Japanese Adverb “むしろ”: Preference, Revision, and Re-evaluation
The practical uses of “むしろ” may appear varied, but they are doing essentially the same thing: another possible answer A exists, and after comparing again, the speaker shifts the focus toward B. The only difference is whether A and B are options, descriptions, or evaluations of the same situation.
“むしろ” Usage ①｜Expressing a Preference for B over A
When two plans, options, or preferences are placed side by side, “むしろ” can directly indicate which side the speaker prefers. This use is especially common with “より.”
- Example: コーヒーより、むしろ紅茶をよく飲みます。
Kana: コーヒーより、むしろこうちゃをよくのみます。
Translation: I actually drink tea more often than coffee.
Coffee is not completely excluded, but when everyday habits are compared, tea is more representative of the actual situation. - Example: 大人数で集まるより、むしろ少人数でゆっくり話したいです。
Kana: おおにんずうであつまるより、むしろしょうにんずうでゆっくりはなしたいです。
Translation: Rather than gathering in a large group, I’d prefer to talk slowly with just a few people.
The sentence compares two styles of gathering, and the smaller group is the option that better matches the speaker’s current preference. - Example: 休日は遠くへ出かけるより、むしろ近所を散歩するほうが好きです。
Kana: きゅうじつはとおくへでかけるより、むしろきんじょをさんぽするほうがすきです。
Translation: On my days off, rather than going somewhere far away, I prefer taking a walk around the neighborhood.
“むしろ” gives the latter choice the nuance of “if I really compare the two, this is actually the one I prefer.”
“むしろ” Usage ②｜Correcting the Previous Label Because B Is More Accurate
When someone’s personality, the feeling of a film, the nature of a job, or an interpersonal relationship cannot be neatly described with one word, “Aというより、むしろB” is very natural. A is not necessarily completely wrong; it is simply too rough, while B gives a more accurate description.
- Example: あの人は先生というより、むしろ友達に近い存在です。
Kana: あのひとはせんせいというより、むしろともだちにちかいそんざいです。
Translation: Rather than a teacher, that person feels more like a friend.
The person’s formal role is not denied, but when describing the actual relationship, “friend” is closer. - Example: この映画は怖いというより、むしろ悲しい作品でした。
Kana: このえいがはこわいというより、むしろかなしいさくひんでした。
Translation: Rather than being scary, this movie was more of a sad film.
“怖い” may describe the film’s surface genre impression, but after watching it, sadness is the stronger lasting feeling. - Example: 今回の経験は失敗というより、むしろいい勉強になりました。
Kana: こんかいのけいけんはしっぱいというより、むしろいいべんきょうになりました。
Translation: Rather than calling this experience a failure, I’d say it was a valuable learning experience.
Things may not have gone according to plan, but when reassessing the experience, the speaker feels that “learning something” is more appropriate than simply labeling it a “failure.”
“むしろ” Usage ③｜Re-evaluating a Situation That Was Originally Seen as Unfavorable
“むしろ” sometimes appears in result sentences that look like “rather” or “instead,” which is where it can easily be confused with “かえって.” However, the focus of “むしろ” is still not that “A directly caused the opposite result.” Instead, after considering both sides, the speaker discovers that a situation initially seen as unfavorable can actually be evaluated differently.
- Example: 雨だったけれど、人が少なくてむしろゆっくり見られました。
Kana: あめだったけれど、ひとがすくなくてむしろゆっくりみられました。
Translation: It was raining, but because there were fewer people, I actually got to look around at a relaxed pace.
Rain would normally be evaluated as a disadvantage, but after the trip, “fewer people and more time to look around” became the more prominent impression. - Example: 一人で参加したので、むしろいろいろな人と話しやすかったです。
Kana: ひとりでさんかしたので、むしろいろいろなひととはなしやすかったです。
Translation: Because I participated alone, I actually found it easier to talk with different people.
Attending alone might initially suggest loneliness, but in retrospect the speaker evaluates it as having made interaction easier. - Example: 予定を詰め込まなかったので、むしろ旅行を楽しめました。
Kana: よていをつめこまなかったので、むしろりょこうをたのしめました。
Translation: Because I didn’t pack the schedule too tightly, I actually enjoyed the trip more.
This is not describing “leaving the schedule open caused a backfire.” Instead, after comparing two styles of travel, the speaker judges the less packed approach to have suited the experience better.
Complete Comparison of “むしろ,” “かえって,” “いっそ,” and “というより”
“むしろ,” “かえって,” and “いっそ” can all sometimes be translated using English expressions such as “rather,” “instead,” or “might as well,” but Japanese treats different underlying questions separately. “むしろ” asks which side fits better, “かえって” asks whether the result ran against the original expectation, and “いっそ” describes deciding to take a different path altogether.
| Comparison | “むしろ” | “かえって” | “いっそ” | “というより” |
|---|---|---|---|---|
| Main judgment | Which side fits better? | Did the result violate expectations? | Which option should I decisively choose? | Which description is more accurate? |
| Common English | rather, instead | actually, instead, only to end up… | might as well, just | rather than saying A, B |
| Comparison target needed? | Usually, but it may be omitted | Not necessarily | Usually some alternative exists in the background | A and B are present |
| Backfire required? | No | A major feature | No | No |
| Decisive feeling | Weak | None | Strong | Weak |
| Typical structure | AよりむしろB | Aしたら、かえってB | いっそBしよう | AというよりB |
▌“むしろ” vs. “かえって”｜Which Side Fits Better, or Did the Result Actually Reverse Expectations?
“むしろ” and “かえって” can indeed overlap in some contexts. Dictionaries also note that both may work when comparing two states. The clearest difference appears in explicit backfire sentences. “かえって” indicates that something was expected to produce one result but actually moved in the opposite direction; sentences like this generally cannot simply replace it with “むしろ.”
✅ 夜より、むしろ朝のほうが集中できます。
I can concentrate better in the morning than at night.
This sentence simply compares two time periods and judges morning to match the actual situation better.
✅ 早く終わらせようと急いだら、かえって時間がかかりました。
I hurried because I wanted to finish quickly, but it actually took longer.
“急いだ” was intended to save time, but it produced the opposite result, so “かえって” is natural.
❌ 早く終わらせようと急いだら、むしろ時間がかかりました。
If you want to preserve “むしろ,” the sentence needs to become a genuine comparison:
✅ 急いで進めるより、むしろ一度確認したほうが早いです。
Rather than rushing ahead, it is actually faster to check once first.
Here, “rushing ahead” and “checking first” are two methods being compared, which fits “むしろ.”
▌“むしろ” vs. “いっそ”｜Reconsidering the Options vs. Making a Decisive Choice
“いっそ” often appears when several options are unsatisfactory or difficult to choose between and the speaker eventually decides to adopt another, more decisive approach. Compared with “むしろ,” it adds the nuance of “after thinking about it, let’s just make this choice.” Dictionaries likewise describe “思い切って選ぶ” as a central nuance of “いっそ.”
✅ 電話より、むしろメールのほうが説明しやすいです。
Rather than over the phone, it is easier to explain by email.
This simply compares two communication methods, without any emotional need to make an immediate decision.
✅ 何度も予定を変更するなら、いっそ来週に延期しよう。
If we’re going to keep changing the schedule, let’s just postpone it until next week.
After repeated adjustments have not worked well, the speaker proposes another option outright, making “いっそ” more appropriate.
▌“むしろ” vs. “というより”｜One Emphasizes B, the Other Corrects the Wording
“というより” can already revise A into B by itself, so “AというよりB” is a complete construction. “むしろ” is not grammatically required. Adding it simply gives B more prominence.
✅ 静かというより、少し寂しい町です。
Rather than quiet, it is a somewhat lonely town.
✅ 静かというより、むしろ活気がない町です。
Rather than quiet, it would be more accurate to say the town lacks energy.
The first sentence simply searches for a more accurate description. In the second, adding “むしろ” pushes the speaker’s focus more clearly toward the evaluation that follows.
▌Should Japanese “Rather” Be “むしろ” or “かえって”? Two Quick Questions
“Between A and B, which one fits better?”
If the answer is B, “むしろ” is usually the better direction.
“Was A originally done in order to produce a certain result, but did the outcome turn out to be the opposite?”
If the answer is yes, “かえって” is usually the better choice.
For a sentence like “After it rained, it actually felt cooler,” both expressions can sometimes work, but the focus changes.
- 雨が降って、むしろ涼しく感じました。
After it rained, it actually felt cooler by comparison. - 雨が降ったことで、かえって寒く感じました。
The rain actually made it feel colder than expected.
“むしろ” sounds more like a reassessment, while “かえって” more readily conveys that an expectation did not work out as assumed.
How Does the Nuance Change When the Same Travel Situation Uses “むしろ” or “かえって”?
Rain during a trip is a useful situation for observing the difference between these two adverbs.
雨だったけれど、人が少なくてむしろ快適でした。
It was raining, but because there were fewer people, it was actually quite comfortable.
This sentence places the evaluation “rainy weather is unpleasant” beside “fewer people made the experience comfortable” and ultimately chooses the latter. The focus is on re-evaluating the trip.
雨を避けようとしてタクシーに乗ったら、渋滞してかえって遅くなりました。
I took a taxi to avoid the rain, but we got stuck in traffic and actually arrived later.
This sentence contains a clear purpose and a backfire. Taking a taxi was supposed to make the trip faster and more convenient, but congestion caused the opposite result, so “かえって” is appropriate.
Both sentences might use “actually” or “instead” in English, but the first re-evaluates the situation, while the second describes events genuinely moving in the opposite direction from what was intended.
Everyday Uses of “むしろ”: Three Conversation Situations for Chatting, Work, and Travel
“むしろ” is not an adverb restricted to formal writing. It appears naturally in everyday conversation when correcting preferences, comparing options at work, or re-evaluating something that happened during a trip.
▌Situation ①｜A Friend Guesses the Weekend Plan Wrong
A：週末は家でゆっくり休みたいんでしょう？
Kana: しゅうまつはいえでゆっくりやすみたいんでしょう？
You want to stay home and relax this weekend, right?
B：家で休むより、むしろ外を歩きたいかな。
Kana: いえでやすむより、むしろそとをあるきたいかな。
Rather than resting at home, I think I’d actually prefer to go for a walk outside.
📌 Grammar Point: A first introduces the option of “resting at home,” and B uses “むしろ” to shift the true preference toward going outside. There is no backfire here; it is simply a reconsideration of preference.
▌Situation ②｜Discussing Communication Methods at Work
A：この件は、先にメールで説明しますか。
Kana: このけんは、さきにメールでせつめいしますか。
Should we explain this by email first?
B：内容が複雑なので、むしろ直接話したほうが早いと思います。
Kana: ないようがふくざつなので、むしろちょくせつはなしたほうがはやいとおもいます。
The content is complicated, so I actually think it would be faster to talk directly.
📌 Grammar Point: Email and direct conversation are both viable options. The speaker compares them and decides that speaking directly is more appropriate, so “むしろ,” rather than “かえって,” is used.
▌Situation ③｜Re-evaluating a Rainy Trip
A：せっかくの旅行なのに、雨で残念だったね。
Kana: せっかくのりょこうなのに、あめでざんねんだったね。
It was such a shame that it rained on the trip.
B：でも、人が少なくて、むしろゆっくり見られたよ。
Kana: でも、ひとがすくなくて、むしろゆっくりみられたよ。
But there were fewer people, so I actually got to look around more slowly.
📌 Grammar Point: A evaluates the rain as a disadvantage, while B offers another evaluation. What becomes prominent is “fewer people meant more time to look around,” so “むしろ” is being used to revise the way the experience is viewed.
Cultural Notes:
- “むしろ” works well when discussing options at work because it does not reject the other person as directly as saying “それは違います.” A speaker can first acknowledge the previous proposal and then say “むしろこちらのほうが……,” making the tone sound more like an alternative judgment reached after comparison.
- “というより、むしろ” is common in interviews, film reviews, and descriptions of people because many impressions are difficult to classify using a single adjective. It leaves some room for A to remain partly valid while revising the description toward the more accurate B.
- “むしろ” itself is not restricted to either positive or negative evaluation. “むしろ便利だ,” “むしろ問題だ,” and “むしろ不自然だ” are all possible. What matters is not whether B is good or bad, but whether the context provides another possible direction for comparison.
How Does Japanese “むしろ” Compare with Korean “오히려／차라리”?
Japanese “むしろ” often corresponds to Korean “오히려,” especially when re-evaluating a situation or indicating that the other side actually fits reality better. However, when “むしろ” appears in an explicit choice between alternatives, Korean may instead use “차라리” or simply express the comparison with “더,” depending on the context.
“오히려” overlaps considerably with “むしろ,” while “차라리” more readily carries the nuance of abandoning another option and choosing a different one. For that reason, in some contexts it is actually closer to Japanese “いっそ.”
◆ Similar Expression ①: Korean “오히려”
Korean “오히려” can indicate that compared with an original judgment, general expectation, or another situation, the actual state leans toward the other side. When used to re-evaluate a situation, it overlaps considerably with Japanese “むしろ.” If the sentence explicitly means “I expected one thing, but the result turned out to be the opposite,” it may instead correspond more closely to Japanese “かえって.”
- Example: 비가 와서 사람이 적었고, 오히려 편하게 구경했어요.
Romanization: bi-ga wa-seo sa-ram-i jeo-geot-go, o-hi-ryeo pyeon-ha-ge gu-gyeong-hae-sseo-yo.
Translation: Because it rained, there were fewer people, so I actually got to look around comfortably.
Rain is normally seen as an unfavorable condition during a trip, but after the actual experience, the smaller crowd made sightseeing more comfortable. - Example: 어렵다기보다 오히려 재미있어요.
Romanization: eo-ryeop-da-gi-bo-da o-hi-ryeo jae-mi-i-sseo-yo.
Translation: Rather than difficult, it is actually interesting.
“어렵다” is not necessarily completely wrong, but after comparing the two evaluations, “재미있다” better matches the actual feeling. - Example: 혼자 여행하니까 오히려 사람들과 이야기할 기회가 많았어요.
Romanization: hon-ja yeo-haeng-ha-ni-kka o-hi-ryeo sa-ram-deul-gwa i-ya-gi-hal gi-hoe-ga ma-na-sseo-yo.
Translation: Traveling alone actually gave me more opportunities to talk with people.
Traveling alone might initially suggest fewer interactions, but the actual experience is evaluated differently. Here, “오히려” shifts attention toward an outcome that might not have been expected, so depending on context it can also carry some of the “expectation versus reality” nuance associated with “かえって.”
◆ Similar Expression ②: Korean “차라리”
“차라리” is commonly used when a choice needs to be made, especially when the original option is unsatisfactory and the speaker decides that another course of action would be better. It is often translated as “rather,” “might as well,” or “I’d rather.” In some contexts, it can correspond to Japanese “AよりむしろB,” but “차라리” usually contains a stronger sense of deliberately choosing the latter option and often comes closer to Japanese “いっそ.”
- Example: 택시를 기다릴 바에는 차라리 걸어가는 게 빨라요.
Romanization: taek-si-reul gi-da-ril ba-e-neun cha-ra-ri geo-reo-ga-neun ge ppal-la-yo.
Translation: Rather than waiting for a taxi, it would actually be faster to just walk.
“Waiting for a taxi” and “walking” are two practical options, and the speaker explicitly chooses the latter after comparing them. “차라리” does not merely say which option is better; it also carries the sense of “we might as well choose this one.” - Example: 계속 고민할 거면 차라리 직접 물어보는 게 나아요.
Romanization: gye-sok go-min-hal geo-myeon cha-ra-ri jik-jeop mu-reo-bo-neun ge na-a-yo.
Translation: If you’re going to keep worrying about it, you might as well ask directly.
Continuing to guess is not solving the problem, so the speaker proposes “asking directly” as an alternative. “차라리” conveys abandoning the first approach and choosing another path, giving it more decisiveness than a simple comparison with “오히려.” - Example: 이렇게 비쌀 줄 알았으면 차라리 집에서 먹을 걸 그랬어요.
Romanization: i-reo-ke bi-ssal jul a-ra-sseu-myeon cha-ra-ri ji-be-seo meo-geul geol geu-rae-sseo-yo.
Translation: If I had known it would be this expensive, I would rather have eaten at home.
After the event has already happened, the speaker compares the two choices again and concludes that the alternative would have been better. “차라리” here carries clear regret and choice, rather than merely indicating that eating at home would have been more appropriate.
◆ Main Differences from “むしろ”:
Japanese “むしろ” has a broader range and primarily indicates that after comparing two judgments, descriptions, or options, one side fits reality better. “오히려” overlaps considerably with “むしろ” in re-evaluation and reverse comparison, but “오히려” can also explicitly describe a result that differs from what was originally expected, in which case it may correspond more closely to Japanese “かえって.”
“차라리,” by contrast, leans more strongly toward actual decision-making. If the sentence simply means “between A and B, B fits better,” Japanese “むしろ” is natural. If the meaning has shifted toward “since A is not ideal, we might as well choose B,” Korean will often prefer “차라리,” while Japanese may be closer to “いっそ” or to a choice-oriented use of “むしろ.” So even when all of them are translated into English as “rather” or “instead,” it is still necessary to determine whether the sentence is re-evaluating something or actually choosing a different option.
The Japanese adverb “むしろ” should not be memorized simply as “rather.” If a sentence is comparing two options, descriptions, or evaluations and ultimately considers one side more accurate, “むしろ” often has a place. If someone does something in order to produce a certain result but ends up creating the opposite effect, “かえって” is usually closer.
“いっそ” adds another layer: decisively making a choice. The English translations may look similar, but Japanese distinguishes different speaking functions. When you encounter “rather” or “instead,” do not immediately search for a one-to-one Japanese equivalent. First determine whether the speaker is comparing, describing a failed expectation, or making a decision. That usually eliminates the unsuitable options quickly.
FAQ
“むしろ” indicates that after comparing several possible options or judgments, the speaker considers the latter one to fit the actual situation better. Depending on the sentence, it can be translated as “rather than…,” “more… than…,” “rather,” or “instead.” It should not simply be memorized as “rather,” because “むしろ” does not inherently imply an unexpected result.
“むしろ” mainly compares A and B and indicates that B fits better, while “かえって” mainly describes an actual result that goes against the original expectation. “夜よりむしろ朝がいい” simply compares two times of day, while “急いだらかえって遅くなった” means that hurrying to save time actually caused a later arrival.
No. “AよりむしろB” is only one common pattern. You can also use “Aというより、むしろB,” “Aどころか、むしろB,” or simply “むしろB” when A has already been established by the context. The key is whether there are two directions available for comparison, not whether “より” appears explicitly.
No, but “むしろ” is not required. “というより” can already revise A into B, and adding “むしろ” simply strengthens the nuance that B is the more accurate description. In ordinary conversation, “怖いというより悲しい” is completely natural; “むしろ” is added when the speaker wants to emphasize the latter evaluation more strongly.
First determine whether the sentence compares two possible directions or describes a backfire. If you can rephrase the question as “Which of A and B fits better?”, “むしろ” is usually appropriate. If the meaning is “I did this expecting one result, but the opposite happened,” “かえって” is usually the better choice. The English translation may use “rather” in both cases, but Japanese distinguishes them according to different underlying relationships.
