I played BotW a lot, and really loved it. I feel like the beginning of the game was relatively easy compared to TotK, I died a few times trying out things, discovering the game and possibilities ; in TotK I died a lot and still do even with good gear and armour (1*-2* armors, 30-40+ damage weapons).
You could say it's skill issues and I would agree with you as I am not a pro player and play games once a week maybe, however I feel like the difficulty curve is far greater in TotK.
That has affected how I view the game to the point that sometimes I think I dislike it (even though the new powers are the best thing they could have added, with the verticality of the world) ; that might also have to do with the much darker ambiance of the game, which can feel frightening (to me) to the point going underground is hard.
Is it just me? Should I just "git gud"?
I felt the same at the very begining, however I missed like the first NPC and explored the whole sky island without unlocking shrines. Afterwards, I did the water temple first and had a hard time both with the boss there as well as the mud thing before you even get to the dungeon. Kind of sabotaged myself there twice in a row, the remainder of the game felt quite easy.
