From a technical point of view ps3 is better, but XBL is more active; though it apparently has more people screaming into headsets.IMHO ps3 has the better exclusives (uncharted, god of war, ratchet and clank, hd remakes etc), the only 360 exclusives i ever hear about are gears of war and halo.
360 has more people using hacks in online games like cod, but that's likely to happen with a more active community. 360s also have a higher failure rate than ps3's.I recommend you look at the exclusives and both consoles and decide from there. Multi-platform games have very little difference between them and run better on the system they were developed for before port.These are usually developed for 360 first though.
Other than exclusives i recommend you get the console that most of your friends have as online play is always more fun with friends.
