@SG854 This is a question you'll never have a straight answer to, lol. I guess you could always go by aggregate scores on places like Metacritic, but that doesn't always mean
you'll like the game.
@Uiaad and
@Taleweaver are right in saying it's pretty much down to personal preference. What kinds of things you look for in a game and what looks engaging to you will trump any advice we could give here.
BUT, if you're looking for suggestions regardless, I'll say there's no "best" one, merely suggestions on which ones to play. For that, I'd suggest any of the following, in no particular order...
Oracle of Ages/Seasons (I prefer
Ages, but that's me)
Majora's Mask 3D (I find the remasters on the 3DS to be superior to the originals)
Ocarina of Time 3D
Breath of the Wild
A Link to the Past (either the GBA or SNES version, both are fine unless you're a purist)
Windwaker (I'd suggest playing the Wii U HD remaster here. Barring that, play the GameCube one on Dolphin with some hacks to bring it up to par)
The Minish Cap
I guess you could add either the Wii U or GameCube versions of
Twilight Princess to the list (not the Wii one), but that game seems more hit and miss with people.
