It depends on the position and I think that it is equal.

you can use rook=5 bishop=3.25 pawn=0.875 and you are going to find that it is
equal.

If you use rook=5 bishop=3.25 pawn=1 you are going to find that rook and 2 pawn
are better than pair of bishops and I do not think that it is correct.

the number that I give seems to cause less mistakes but still you cannot say
what is better without special rules.
