I can understand controller issues though, the defining choice for me when I bought me SNES was to have a workable controller for SFII. Its not that I dislike the Genesis controller but trying to play fighting games on it was a nightmare without a special controller.

I think the only controllers I've ever disliked were the Sega Saturn (flimsy and never felt like it had good response time), the N64 (Just no...), and the Atari Jaguar.

I feel all three major console systems this generation have pretty good controllers overall.
