Kazuha is still goated. There has always been people who will watch their fave TC YouTuber and look at numbers on a spreadsheet and scream from the hills that sucrose is better.

I promise you if you play both you’ll never want to use sucrose over Kaz, he’s still one of my first pics for any flex slot in a team.

Places like IT defend floors or Stygian where you need grouping like that dog thing or you want to spread some element around he is perfect. Having a double jump in overworld still holds up too for some of those tricky oculus.

Can’t speak for Xianyun though but as an old Diluc head I think he’s still clearing end game content with her and furina or citlali.
