I was wondering what the differences (if any) between these two version of Metal Gear Solid 2 were.

I've just finished a game (Genji: Dawn of the Samurai) and in keeping with my one (main) game at a time rotation, I've decided to start MGS2. For some reason, I have both the XBOX and the PS2 version, and I'm not sure which I'll go with.

As of now it's just a question of whether I want to use a wireless DS3 controller, or a wired XBOX Duke controller (I'm leaning towards the Duke, honestly). So then, is there some other tie breaker I should know about, or are they essentially the same game?
