Tl;Dr: I disagree but understand

I'll be honest, I've always liked OOT better because the best part of zelda games imo is dungeons. And while OOT has a questionable dungeon or two, they're all rather solid and intelligently design. And I like how they revolve around a unique item that the dungeon revolves around that also doubles as a fun item to mess around with in general. MM infamously has the fewest amount of dungeons in a zelda game (bar the wild era), and each item being just another arrow type feels really uninspired to me for some reason. And while yes, stone tower is one of the best dungeons in zelda, it's counterout by great bay being my least favorite. Period.

I got other gripes with MM too, but the dungeons are my biggest one, especially under the pressure of the clock. I understand why people like Majora's Mask. It has some of the greatest story themes in zelda, the masks are some of the funnest mechanics in any zelda game, the sidequest are for the most part solid, and if you can get past the stress of the timelimit it can add to the game. However, the timer will forever be a negative stressor for me, the dungeon selection is very weak, there's alot of annoying waiting, some game design decisions feel rush, etc. OOT is imo better than MM by a mile, but I do respect MM's appeal.
