Well, I have both machines and I'm pretty sure I'll get the PS3 version (unless it's somehow significantly crappier than the X360 version). My reason for this might be silly, but in the past four months or so I've _tried_ to play on the X360 and the bastard's just so FREAKING LOUD! I mean the humming and whirring and whatnot distracts me so much I'd have to turn up the volume so loud that I couldn't play it at night or the neighbors would have a fit.
At 8 feet away from my tv needs around level !35! to cover 360's noise
