While I'm sure that the fact that I grew up with the US Super Nintendo controllers has something to do with my preference, I think an argument could be made for it being the superior iteration of the SNES controller with nostalgia removed from the equation.
For me it all comes down to the concave X and Y buttons. They really make all the difference, and the end result is near-perfection when it comes to controllers in the pre-dual analog stick era.
The only thing that the Super Famicom controllers have over their American counterparts is the color scheme. A Super Nintendo controller with the Super Famicom button colors would be absolute perfection as far as I'm concerned.
What say you, GAF? Does everyone just prefer the controller that they used as kids, or do some of you prefer one over the other regardless of that factor?
