I've played them all except Ocarina of Time, which is disgraceful I know, I really need to grab it off VC and see what the fuss is about. When I think back to playing ALTTP on the SNES I remember it as being the best one but having actually gone back and played it again recently I would now have to choose Wind Waker, closely followed by Phantom Hourglass. The combination of the lovely cel-shaded graphics and great music just create the most magical atmosphere for me. Didn't take to Twilight Princess so much, the world was too dreary and had none of WW/PH's wonderful charm. I haven't finished Spirit Tracks yet so can't give a verdict on it. Oh, and Zelda 1 is still awesome too! :D
