What is your favorite controller?

[NICKtendo DS]

My favorite controller is the Gamecube controller. I haven't played much Playstation or X-Box, but I know the buttons always confused me on both sets of controllers. The placement of A, B, X and Y on any X-Box controller and especially the shapes on the Playstation controller. I can never for the life of me learn where the square and circle buttons are. I always have to look on the controller for those.
