I also feel like TotK is easier than BotW, only in the early game was I cautious of some enemies; in BotW I was almost always wary of facing guardians. But I also enjoy that the map doesn't feel as "empty" in TotK and I can just explore more relaxed.
There are some QoL improvements in TotK that I think I would struggle not having if I went back to BotW, like being able yo use the Purah Pad while gliding.
I did enjoy the story telling of BotW more, it felt more emotional to me.
