They both look the same to me (i.e. very minor differences which I don't care about as I don't worry about console comparisions and get down on my hands and knees peering at the screen).
If I get it I will with PS3 as that's the console I have. I doubt any normal gamer on either platform is going to notice much difference in play.
I guess achievements on 360 could be seen as only major difference (I assume it has them) but I actually really don't like achievements (although they're not the reason I don't have a 360).
Personally I'm just glad another good game has been delivered that seems to have been well developed on each platform - hopefully all PS3 and 360 owners who like this game will find it a good play and a worhwhile purchase.
BTW regarding the 30 fps vs 60 fps for EA sports games this was clearly EA's issue - at most I would accept the engine design was hard to port to PS3 but nonetheless EA have to take the blame for chosing not to put in the investment/effort required to achieve a resonable level of parity. Most major cross-platform games have shown this can be achieved very well (COD4, AC and now Burnout Paradise and I would add DMC4 from what I've seen) so hopefully going forward developers will realise they must aim for this level of parity.
Try to be reasonable... its easier than you think...
