I had to vote for Bayonetta. I can only really imagine voting for it or Vanquish out of the five I've played. Vanquish is pretty much just as strong of a game as Bayonetta if you compare them minute-to-minute (actually, Vanquish probably has better pacing than Bayonetta, which feels kind of disjointed even ignoring the vehicle sections), but I love how packed full of content Bayonetta is. I wish Vanquish had something to unlock other than God Hard and the challenges, although those are still pretty substantial.
Madworld is pretty weak. It looks cool (although I have to admit I have a hard time reading what's going on sometimes), and the soundtrack is awesome, but combat is way too simplistic. I don't think anything in the game is interesting to fight, and the game gets repetitive way too quickly for being as short as it is.
Anarchy Reigns is a lot of fun in multiplayer (although it does feel pretty unpolished), but as a solo game it feels kind of lacking. The bosses are very fun on hard, but the standard enemies and midbosses are really boring to fight no matter what difficulty you're on.
Metal Gear Rising is solid and has some moments of greatness, but it feels too flawed to be on the same level as Bayonetta and Vanquish. The camera is incredibly annoying, and damage on your attacks always feels kind of off (and having to deal with a separate attack strength stat for your weapon is lame). It's still a really good game but I don't think it's comparable to Bayonetta or Vanquish.
I haven't played Infinite Space (too expensive and I don't really like RPGs that much) or Wonderful 101 (no Wii U, but I'm sure I'll get one eventually).
