I vote for 360, even if I'm on my 6th console (maybe 7th, I've lost count) and it just scratched the shit out of my GTAIV disk.
Games man, games. 360 have them in spades, my ps3 has only been used for a blu-ray player, I've played 3 games on it.
360 has it all, except reliability, but has a 3 warrenty for that, and takes about 14 days to get back after sent off.
