The graphics differences between PS3 and Xbox 360 graphics is too minor to notice anyway.
I remember people made a big fuss about how Street Fighter IV was pared back on the PS3, and I own both versions and I never notice any difference. The game is pretty much the same the PS3 even has a Championship mode the 360 doesn't. Even Bayonetta which was said to be much worse on the PS3 plays just fine, indeed the 360 performs better but the PS3 game is just as awesome... Same goes for the games that are worse on the 360, like Final Fantasy XIII, the minor differences take nothing away from the experience.
Back in the 16-bit era, I remember games lacking characters, content and player modes in some multiplats (Final Fight Super NES had no 2-player support, etc...).
These days a game lacks a few textures on the ground and people think it's a deal breaker? It is not, and it goes unnoticed unless you read about it.
