I’ve come up with these conclusions on these aspects:
Graphics: Its the same, you are retarded if you can see a difference. Even if there is a difference, it’s barely noticeable.
Price: The PS3 might be more expensive to buy, but that is all you have to pay for besides games.
On Xbox you have to pay for Xbox Live, batteries for your controller, and a cooling fan so it doesn’t overheat.
Games: Xbox might have some cool games like Halo and Left 4 dead, but that’s about it. Playstation has Killzone,Resistance, Motorstorm, Gran Turismo, Little big planet, God of War and Heavy Rain.
Controllers: They are both wireless, but an Xbox control needs batteries, which require effort and money.
PS3’s are more reliable, because there are more cases of RRODs than YLODs.
