PS3 or 360, Which system Should I get these games for?

[Blacksaber]

DeUS eX:Human Revolution Doesn't Matter
Batman: Arkham City Doesn't Matter
Dark Souls PS3 (Safer to go with the console the developer is more familiar with.)
Dead Island Doesn't Matter
Skyrim 360 (Though all Best games are buggy the 360 versions seem to have a little less problems.)
Dragon Age Doesn't Matter
Battlefield3 PS3 ( Free extra Content.)
