Not OP, but Is that bait? Lol, it's written in rust for a start!

Kidding aside, it's not "better." I switched to alacritty from urxvt years ago because it was easier to configure and came with the promise of speed. I tried out kitty when it was new and still a bit raw, but haven't given it another fair shot.

Ghostty is also on my list to try now too.
