In the real world Ocarina of Time is a thousand times more well known than Majora's Mask and held in a thousand times higher regard. On forums like this it may be hip to like Majora's Mask better than Ocarina of Time, but the latter game is the one that was 'legendary' to the average consumer.
Majora's Mask could probably beat Ocarina's first week because it has five times the install base to sell to, but I don't see it winning lifetime sales. It will likely have a better ratio though; Ocarina will end with 4m at most, about half the original, while Majora's Mask should do between 2.5m-3m, almost matching the N64 original due to it being a more 'core' game.
Wind Waker's remaster will remain the worst contestant though, even when counting A Link to the Past on GBA, both in absolute sales as well as ratio. I think WWHD will top out at 2m at most. Which is still good in any regard.
