I finished TOTK. Took me a bit over 60 hours***. I did 76 shrines, got two extra Stamina wheels and 18 hearts. Great game worth a play-through, but not really better than BOTW, imo. Both games are 8/10 for me. Just way too bloated (especially TOTK), and I still don't like the breakable weapons/shields. I hated the Depths too, just drab and dark (and endlessly huge) with that annoying gloom everywhere -- not very enjoyable. Dungeons were pretty good overall, but I didn't like the last one at all, and the lead-up to the final boss was more annoying than fun. No real challenge in the game once you upgrade your armor and cook a bunch of stuff. I did like the shrines in this game, though.
I still strongly prefer the classic Zelda games: Zelda II, A Link to the Past, Ocarina of Time, Link's Awakening, and Wind Waker. All of those are 9/10 or 10/10 in my book.
***In contrast, BOTW took me about 45 hours.
