PS3 owns with their exclusive titels.
But for cross platform, there have not been a single game released in the past 5 years, where Xbox is not better then PS3. Not once.
Only exceptions is Dark Souls, which can be argued which version is best. But thats a port from PS3 to Xbox.
But in general, cross platform games are always best on xbox for reasons I have listed in other threads.
Its just common knowledge and nothing to argue about.
Again, PS3 exclusives kick [censored] and its sad that the PS3 is so complicated to work and program on that no game developer actually fully use it for the cros platform games out there.
But the complications to programme and develop for it, is also its downfall.
