〜と〜とどちら
Between A and B, which…? (comparison question)machine translation
FormationNoun A + と + Noun B + と、どちらが〜ですか
To ask a comparison between TWO things, use: AとBと、どちらが〜ですか. The answer usually uses the comparative pattern: 〜のほうが〜です.
The special point: whether you're comparing people, things, places, or times, the question word is always どちら — it does not change to だれ or どこ as in ordinary questions.
In casual speech, どちら is often shortened to どっち. When comparing three or more things, switch to the pattern 〜のなかで〜がいちばん.
