WOZ has a lot of nice features and is a beautiful machine. However, it just doesn't give me the rush of excitement that Tron does with it's challenging modes, especially SOS. I also think that Tron does a better job of incorporating the movie into the game with it's music, quotes, and image sequences. The only thing that I like about WOZ better than Tron would be it's display, but having said that, I'm surprised there's not very much of the movie mixed in with the game.
Tron rules!
