knight - bishop?

Suppose each player has 3 pawns, one player bishop, the other player knight, pawns in even position... what is better?

I think it depends on the position of the pawns and the kings, of the promoting squares.
Asking Stockfish ?

I was thinking that the bishop can go to half the squares only

Everything at one wing a knight is fine usually. But it depends on the concrete position of course.

Why do you think there is a clear answer to a question that has no one concrete reality?
You either take these evaluations in a case by case (specific/concrete positions) basis or specify much more information to then get by with a "probably in such and such situations the bishop is better". The more general case of them all is the one you presented: knight and 3 pawns vs bishop and 3 pawns - I don't know the answer (though I suspect it) not even in terms of "probably this or that is better" - and there is no shame in that as it is not really useful (or only very marginally useful), to think about any specific situation like that.

In endgames, Bishop is generally more powerful than Knight.

But with complex pawn structure, Knight can be more powerful than Bishop.

@TheBeastWithin i never wrote that "there is a clear answer", but maybe there are statistics and probabilities

@vaibhav2016 thankyou, you understood my question... 3 pawns and bishop vs knight is endgame... or

@rkwe4477 Ok, I assumed as I should by the way you wrote it. By asking "what *is* better?", there is the implied assumption that the answer is a clearcut "Bishop/Knight/Equal" - You should rephrase your question to something along the lines of "What *is probably* better?", if you don't want to be misinterpreted.
Still, what I said about the answer you are looking for in terms of "X is probably better", stands.
