Should i get battlefield 3 on ps3 or xbox?

i know it will be the best on pc, but lol i don't have one and i am not gonna pay $2500 for one. I have a ps3 and an xbox and all my mates play pc (i don't give a ****). Im gonna get it on either of these consoles and i need help to choose. Dice have said that between the 2 consoles , it will run best on ps3, to prove their statement they had live b3 betas and demos at E3 free to play ON PS3 not xbox. They said there will be better graphics and a faster game engine on ps3 so SOMEBODY PLZ HELP. P.S. I HAVE BEEN TOLD ALL OF THIS BY PS3 FANBOYS SO IT MAY BE FALSE. PLZ CORRECT ME AND TELL ME UR OPINIONS/ WHAT U KNOW!!!!!!!!!!!!
