Having played both, both online, I'd still go with the 360, the PS3 is way overpriced, has a small online community and almost all of its 'exclusives' were nicked by the 360 anyway. 360 costs less, and although the online isn't free, it's £3.20 a month.. some people would spend that on a couple of mars bars tbh. Sure, you get a few american nubs on it but you get over that pretty quickly.

360 360 360 360!
