Well, this would depend on whether you've played TLoZ before, if you're gonna play all of the 3 games for the first time, I'd suggest ALBW first, seeing as it was the simplest of the 3, and gives you a good idea of the lore of Zelda, and the wall-merging mechanic is really cool (in my opinion).
If you don't like the top-down perspective, and are trying to decide between MM and OoT, I'd suggest OoT first, because the story is more streamline (kinda) compared to Majora;s Mask, but either way, they're all really good and can be played in pretty much any order.
Or you could wait for Tri-force Heroes. ._.
