I loved Majora's Mask, personally. The sheer amount of content that game contained amazed me, even when I go back and play it today. The time mechanics were unique (to my knowledge), and the game was significantly harder than its brethren (though still not that hard).
Also, had some of the coolest glitches in the Zelda games. Riding Epona as a Goron, anyone?
