Going by the majority of user feedback and user reviews I'd suggest The Fight Lights Out. And the controls, contrary to a great deal of the reviews, work fine. When I read the first two reviews from Video Gamer and IGN I wrote it off as a load of old bollocks with broken controls but the iWaggle video and several other videos on youtube demonstrating the controls (including the one I've just linked to) changed my mind completely. I've now ordered it and can't wait.
I think the majority of the lower scored reviews are down to one of (or even a total or mixture of) three things: reviewers not being able to punch their way out of a paper bag, reviewers struggling to understand or implement the RPG elements of the game and/or reviewers not having the skill to play a game that doesn't have a fixed distance between the fighters.
It's not a 9 or 10/10 game by any means but the average user review score I've seen makes it a strong 7/10 game and worth a purchase.
