Tears did improve a lot of things, but not everything.
Durability is a bit better in TotK thanks to the fuse system. However the UI still feels it was designed for the WiiU gamepad, designed for touch screen controls. It worked in BotW yet in TotK so much stuff is added that it becomes very unwieldy and you end up only using a few things as the only useful sort is on most used or most damage for fuse.
Also the sages were more a liability in TotK than any help. The AI keeps putting them in your way, often screwing up what you're doing. The champion abilities in BotW were much better.
TotK also lacks challenge, gets very easy after the start. The end battle is more epic in TotK even though it still falls flat if you leave it too long. Enemies scale better in TotK, however it's still just adding a bigger health bar to the enemies. Plus the OP puff shrooms and muddle buds make every encounter rather trivial. Or you can simply summon an array of beam emitters and sterilize any camp in seconds. The only decent combat was in the proving grounds. And the Guardians were awesome in BotW, nothing like that in TotK.
Story delivery was a disaster in TotK. Far too easy to get big plot points spoiled early by finding things out of order. The memories were done better in BotW than the tears in TotK. Plus Link keeping his mouth shut while he already knows everything just felt stupid. At least the game acknowledges it at one point.
Well you never asked and I can't volunteer information. Got it about 100 hours ago...
TotK is the better sandbox, BotW is the better action rpg and survival sim.
I enjoyed both immensely, even though BotW left a bigger impact.
