What is best two rooks or three minor pieces? ( In different scenarios)

Yes.

rook is 5
knight and bishop are 3
2*5 > 3*3 :D
but it depends on position

It's a very broad question. Obviously two rooks are worth more but that's not always important. It's based entirely on the position. Do you have an example scenario?

Which side do you prefer?

White, Re7 and the f pawn looks like it falls. Although Ne4 might be annoying.

Values are relative, and should not be used once you gone beyond simply learning how to move the pieces.

There are times that having 2 Bishops, especially if both are uncontested, meaning opponent has neither Bishop, where they could be as strong as a Queen together, even though they are only worth 6 on the point scale.

In another game, having the 2 Bishops may not be worth any more than having 2 pawns.

So it all depends.
