For me it's Breath of the Wild hands down. Don't get me wrong, I love Ocarina of Time, for a long time it was my favourite and is now my 5th favourite. I will say that OoT definitely has the superior dungeon design, though I don't mind the divine beasts at all and they work really well for the world they were put in. And OoT does have the more memorable soundtrack, but again BotW's sound design works really well for the experience we're meant to have.
However BotW has a far superior world, not just because it's newer and bigger, but there's also so much to do in it. As a teen, I was wowed by OoT's world, but there is really not much to do in it outside the main story/areas that are actually enjoyable. In BotW, I enjoy the exploration, I enjoy scavenging for ingredients, hunting down ore and treasures, and since getting the Korok mask, I also actually enjoy hunting down those little guys, I enjoy the shrines, the camps, stables, towns, everything I come across really. BotW also has the more enjoyable gameplay, I absolutely love the traversal and how you can tackle things in basically any order you'd like. It's the same reason I love ALBW more than OoT, the openness of the world and how you can choose the order you do things.
