I like them both for different reasons and in different ways. In BOTW I liked the champions better, felt more of a connection to them. Also Revali’s Gale was the best. In TOTK, I am really loving the device building and fusing in general. I miss some of the weapons from BOTW but it’s great being able to fuse different objects for different effects.

You can cheese both in various ways if you want (Revali’s Gale, or a Hover Bike, can get you pretty much anywhere).

TOTK seems to have a lot more stuff around everywhere, on the ground, in the depths, and the sky. It’s even more fun to explore than it was in BOTW in some cases. Also Tears of the Kingdom / Tiers of the Kingdom is a great pun/double meaning.

Also the froggy suit finally lets you climb wet surfaces (and ice) without slipping.

I don’t like the grinding materials to upgrade armor in either one, though. So TOTK wins because I’m a cheating cheater who refuses to update the game so I can keep duping materials as I don’t have months to spend hunting down and killing monsters.
