I'm one of those guys who got badly burned by the Xbox 360 red ring fiasco early in the life of this console generation, so my perspective is tainted. I play (most) multi-platform games on the PS3 purely from habit. The exceptions are the rare FPS I play and Elder Scrolls titles.
The PS3 is fine I guess, but there's little to distinguish it from the 360 at all other than Blu-Ray playback. I mean, it's fine. You know?
