Are the PS3's graphics better than xbox 360?

Well I have played both games and done some research and the ps3 graphics are alot faster and much more clear than the Xbox 360. My information to back this up is i am a game tester and researcher. Also what I know about the XBox is that it went the same way as Wii did and attempted to put yourself in the game. Wii was also going to make a fully new system called "attached" so not to start and problems but XBox needs to start going it's own way like the ps3 and Wii.
