Why is that wild? It's okay to prefer BOTW over TOTK (though why is beyond me) but you can literally do everything in TOTK that you can do in BOTW in addition to a million more things.
So by the very definition of obsolete BOTW is made obsolete. If you like exploring a self-contained Hyrule with your trusty steed or your good ol' feet, you can still do that in TOTK.
Unless you prefer some specific things that have been removed in TOTK, like the Guardians, Revali's Gale, the Divine Beasts, or whatever, then sure, but mechanically speaking TOTK does everything BOTW does + a whole bunch more.
I would say A: the shrines were way more imaginative, varied and fun in BotW.
which is most likely down to the fact that the Sheikah Slate abilities were just way better suited for interesting puzzles.
B: the devine beasts were better designed than the temples in TotK, and while they did add dungeon-like paths whenever you go to a temple, which were a great idea, the temples themselves were pretty meh.
C: there's way less sens of adventure due to the ability to basically just fly across the whole map right from the start.
I get that they did that most likely to accommodate players of BotW, so that there's a sense of progression from one to the other, it still made the world feel less special in a way.
D: going back to the sheikah slate abilities, these not only made for more interesting puzzles than the arm abilities in TotK, but were also just way more fun and useful to use in battle. but that's also true for the special abilities you get after each beast as compared to the ones you get after the temples of TotK.
E: TotK feels almost bloated. there's just way too much going on everywhere, it's getting dangerously close to feeling like a Ubisoft game, where BotW was way more focused.
that's most likely a side effect of it being so similar and of it reusing almost everything from BotW.
Nintendo clearly had to compensate for that by just adding more of everything. but IMO what made BotW so appealing is the simplicity and the fact that almost everything in the game was designed with free roaming exploration in mind.
so in my opinion there's a lot that makes BotW more appealing than TotK.
I would recommend everyone to not play TotK first and instead absolutely play BotW.
