For those of you saying ALttP is too much like OoT, remember ALttP came FIRST. OoT is the one that has a milked storyline, not ALttP.
As for which game is better, that'd be TMC by far. Great, original storyline, cool moves to learn, cool dungeons and bosses, and it even has a lot of character interaction and depth when you go around fusing Kinstones. ALttP is fun, but it's basically, go do this, then go do that. There's hardly any character depth and not much to do besides the main story. In TMC, you could do practically anything you want between dungeons, from learning new sword techniques, fusing Kinstones, exploring secret caves, or just mess around.
