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”?
It's not difficult as much as it is tedious to fight regular mobs by just hitting them with a weapon since they are so spongey. You're intended to use all your gimmicks in combat to make quicker work of them.
I found running in circles around large hoards of enemies and letting my champions do my dirty work was pretty effective. Shooting muddle buds and waiting around is just as boring.
