Does batman arkham city look better on ps3 or xbox 360

It really depends more on the HDTV they are connected to and how far you are away than whether they are the Xbox 360 or PS3 game. There is a much better picture difference between HDTVs than the games and there consoles. You did not ask what has better graphics and the differences are very minor you asked what looks better. You can see more detail 14 inches away from a great Monitor than 14 feet from a huge wide screen HDTV
