I believe the hip slang our boy Denmark is using stands for "Greatest of All Time" dear chadmonkey.
Personally my favourite is the gamecube just because for mine it's by far the most comfortable controller I ever used.
This generation it depends on the game, 360 by far the best pad for FPS games and strangely for Fifa, however is utterly and completely gash for fighting games. PS pad is the king for fighters as far as pads go, not so much for FPS, but that's just personal preference to where I like things for certain games. I hate having the left stick down low for shooters, but find the 360 pad way too big to play fighters comfortably, and the D-pad on the 360 is the worst d-pad in the history of consoles.
