Mostly what I'm concerned about is online content. I don't want to look for a CAW on one that's on the other, and I'm leaning towards the PS3 version if only because I don't have to pay for online, but if the online is worse...
As an owner of both systems I'll tell you that Xbox live is geared more towards social networking whereas psn is pretty basic, dull & plain. You don't have much freedom to express yourself. Xbox live you can view friendlists of friends, more people have mics, you have the option to give player reviews( you can choose to either prefer or avoid anybody for a number of reasons), you can't even send voice messages on psn(which is probably due to the fact that the system itself doesn't come equipped with a mic). The psn certainly has the upper hand when it comes to price since it's absolutely free of charge, & you may not have to deal with all the ridiculous hacks which may not even be an issue this year. The ps3 overall is a great system, my only gripe is that the psn service is not up to standard when it comes to being social. So if this is of any concern for you at all carries any weight towards your final decision then imo the 360 is definitely the way to go.
Who wouldn't want an inbox full of ragequit hate messages from idiot online gamers? You talk of the social aspect of it, when let's face it, 80-85% of people playing online act like total "d*ckinthebootyasses"...ESPECIALLY these WWE games, where being on top of the leaderboard is so vital that people who do any underhanded tactic they can to get there.
Presuming there isn't any "modification" made to the 360 version, then you have two games with the same options, both gameplay and creativity wise. The only aspect then that's different between them then is the ones mentioned in the quoted text, of which I don't see as being an advantage at all. Every online interaction you have on this game isn't going to be against your buddies, unless you're specifically going to be playing Player Matches and not Ranked ones, and in that, you better be ready to dodge a whole lot of online BS from all the cheaters, trollers and crybabies.
At least with the PS3 you don't have to hear
