Well, I really like the FPS's on platforms (GCN, Xbox, PS2), but I like the PC versions somewhat better. Some of the controls of platform FPS's are horrible, but if it's the same game on PC, its actually fun and easy to control. After playing Halo on PC for a while, I played Halo Xbox and I thought, "Ughhh... These controls are horrible!". Plus, I get to mod the games easily.
