[noun] + と + [noun] + と、どちらが + [i-adj] / [na-adj] + ですか [noun] + と + [noun] + と、どちらを / どちらに + [verb (polite)] + か [noun] + のほうが + [i-adj] / [na-adj] + です
AとBと、どちらが… asks which of two things is more something: "which is faster, A or B?" Each of the two nouns takes と, a comma follows, and どちら with the adjective or verb asks the question.
どちら is a question word, so it takes が, never は.
The answer puts のほうが after the one you choose. If you can't choose, say どちらも.
どちら takes whatever particle the verb needs: を for an object, に for a destination.
These go beyond the polite question about two nouns.
In casual speech the second と often drops, and どちら becomes どっち.
To compare two actions, turn each verb into a noun with の.
どちら is only for two. For three or more, use のなか中で with どれ, なん何, どこ or だれ.
