Contoller/Console better for FPS than KB+Mouse/PC?!?

Mouse+keyboard for the win. especially for fast shooters like UT or Team Fortress 2.

I know this thread is about FPS, but while playing Gears of War on 360, I didn't think it would be that better with mouse+keyboard, cuz the game is kinda slow. Then I tried UT3 and it was really hard to aim, I just gave up and played on PC.
