Which Is Better Bishop Or Knight ?

Bishop and Knight has the same points(3)

Offten on endgames I think Bishop Always wins.

We can win with 2 Bishops+King vs King
But I think you can't do the same with 2 Knights + King vs King

-Bishop can move freely diagonaly 
While Knight has a pretty compliated moves 
-Bishop can only move in one coloured square
While knight can move in every square

What do you think and what is your analysis ?

It's like asking whether a hammer is better than a screwdriver. They do different things.

Bishops in open games and knights in closed games are better.

most people will choose bishop most of the time.
