Majora's Mask sucks. Half the bosses are awful (and there are only 5 of those), the game does a terrible job teaching the player how to play the game, the dungeons are average for the series at best, and most of the side quests are babytown frolics and can be completed in ten minutes.
The only reasons people like Majora's Mask is because the story is really "edgy" and "artistic" (it has a slightly darker color palette than Ocarina, which automatically makes it a better game) or because they're hipsters who desperately refuse to accept that Ocarina has far superior design in every facet of the games.
And most of the people who think Majora's Mask is TEH BEST ZERUDA EVAR also beg for total nonlinearity in future titles, while glossing over the fact that Majora is as linear as they come.
Man, it feels good to get that off my chest.
