i think quality>quantity or size. My favorite dungeon in OoT has always been the forest temple, I love fighting phantom ganon and the whole dungeon has a nice charm to it, the first time playing through the game the forest temple was so cool to me, because you were adult link now, more powerful, new items, and new weapons, it was almost a whole new game. And you can make it through that temple in half an hour if you know what you are doing. But then you have the water temple, I hate this temple more than any other part of any other zelda game (great palace is the only exception) its very large in size, but the puzzles don't make you think, they are just annoying. When you forget a key in the forest temple i just let a wallmaster grab me or save warp back to the beginning of the dungeon and collect it. but when i forget a key in the water temple I have to begrudgingly go through the whole temple again to get the water to the right level. The water temple was a game breaker for me until i was almost 12 years old, I would get stuck there for weeks, and I eventually just gave up and restarted the game and played to the water temple again. (rather rinse and repeat for 3-4 years) The other dungeons aren't as memorable to me because I didn't ever play through them until I was a teenager, I fully blame the crappy water temple for that.
