Microsoft intentionally makes defects to make you buy another one after your warranty.
Also, the 360 has the potential to disable your game disc (Scratch).
I'd go for PS3.

Once I had Fable II there were no scratches whatsoever on it, so after a few days play I noticed that the disc had become unplayable. I took the disc out and looked at it the amount of scratches were unbearable thankfully though, wiping it with a soft cloth helped. I also agree that Microsoft put in the red ring of death intentionally. Mines broke down just around 3-4 months some guy tried to fix it but there was problem after problem thats what made me think Microsoft con you. I got a different 360 with 10 game, bout 6 months old and unlike my old one it didn't let off a revving noise.
P.s, The new batman game? Had it for 2 days strange stuff started happenin' in house think it's cursed just like that Dark Night movie. Also had a weird glitchy problem, got up to this point in the game and the screen went weird thought it was another RROD, it wasnt and it prevented me from going further, just a word to the wise.
