Your understanding me wrong. If I had to chose which game I would recommend more, I would never be able to answer. I'm saying I consider OoT more epic than MM, and that is why I personally enjoy playing it more. Epicness usually means nothing in my opinion on games...Legend of Zelda and Metroid...
It depends on your tastes. Majora's Mask WAS the origin of my username because it had the coolest bosses and side quests. Ocarina of Time was way more epic. NOW adays, I'd say that epicness owns all else and say oot is better.
