You should take reviews of stuff like consoles with a pinch of salt, the only way to tell it to get your hands on each and make up your own mind.
If I get either it will be a PS3, purely for Gran Turismo, if the GT series were available on the PC I wouldn't have a PS2. RTS and FPS games just don't work with a joypad IMO, and most driving games that are released these days have stupid arcade physics. Now the GT games' physics are hardly Grand Prix Legends but they just feel right to play. So long as they fix the drift angle issues with the physics engine in the next GT I'm happy
