Both games are nearly perfect, and obviously so similar, so I'll be reviewing this by comparing it to its predecessor.

main quest: TOTK
side quests: BOTW
mid quests: BOTW but just barely
shika slate abilities: TOTK obv but I miss stasis
champion/sage abilities: BOTW
final boss and ending: TOTK by far
overall art design: BOTW (love the ancient tech)
shrine puzzles: uhhhhh. not sure tbh. both good
you can build a house: TOTK
"dungeons" (divine beasts/temples): BOTW by far except shout out to Colgera. ily Colgera

Overall best gaming experience: super hard to decide tbh if you want to play one you should play them both!!
