I guess I should clarify that I quite enjoy SRS Tetris games as well and think of them as a mechanically distinct game from classic Tetris. Center 4-wide is kind of the culmination of the complaints I have about it in a competitive format though -- since it's so powerful, lots of top level matches basically only comes down to who can execute the 4-wide better, which to me isn't really competitively interesting. I think Puyo is the superior versus-style puzzle game, since there's a lot more thought that needs to go into stacking Puyos, sending harassments, timing attacks and managing your resources than in Tetris, where you basically just need to out-DPS your opponent with TSD/TST/combo setups as fast as possible.

I definitely have more traditional tastes when it comes to fighting games, though. As far as Street Fighter games go, I don't think anything has surpassed HF or ST, nor do I think anything ever will with Capcom's current fighting game direction. I do love me some Guilty Gear and Marvel 2/3, though. DBFZ was fun for a week and I LOVE the polish that it received from ASW, but the game itself is sort of bland and repetitive due to its simple universal mechanics.
