I have neither console but having played both, I think I'd have more interest in owning a Wii. I already have a lot of GameCube games (along with a few others that I would play if I had a 60Hz television, e.g. MP2) I could play again using it and there are a number of games for the Wii that I would rather play, compared to relatively few 360 games. I don't have a great deal of time to be a serious online gamer to go for all the achievements and whatnot from 360 games either. So a Wii it is. I wouldn't mind a 360 though.
