Do you hate good graphics and controls?
The Classic controller would be the best choice pad out of all three consoles.
I beg to differ. That clumsy, vestigal wire chained to the wiimote I've always felt was a bigger pain in the ass than if it was wired to the Wii. It still lacks 6 face buttons.
I can't vouch for the d-pad, since there isn't a fighting game I'd actually pay money to play today on the Wii, whether on VC or available through retail.
Really? Even with SFII Turbo and KOF 94? I know 94 kinda sucks, but it's still a good game. As for the pad, I prefer it over the other two pads as it feels like a slightly larger SNES pad, and I always felt the SNES pad was better for Street Fighter games.
I haven't moded my 360 pad (I haven't even turned the machine on in 6 months) but I hated the pad once I played SF on Xbox Live Arcade. It felt clunky and horrible. It's perfect for 3D action games and shit like that, but not for fighters.
I was going to make the exact same point, although I liked the Dpad of the PS2 pads, I can't imagine those spring loaded shoulder buttons will make play any good.
