I like them both.
The PC for WRPG's, and MMO's. The consoles for action games.
I have moved primarily to consoles in the last few years, because games have moved there. I follow the games, and the best games currently (MGO, GTA4, GT5:p, F2, Uncharted, R&C, MA (for now), etc... can only be played on consoles.
I love games, I will buy whatever I need to in order to play them :)
