Apart from the granular blur control. It was mainly the ligatures support, Alacritty’s developer doesn’t seem too keen on it. And it seems to be the only terminal that renders the ANSI blinking escape code properly (although I don’t think it distinguishes rapid and slow blink). I think it’s a cool feature!

Unlike OP, I hardly use WezTerms features. I have hidden the tabs away and just use the old vim+tmux combo. So my config is just 25 lines. There was no weird colour interaction issue that alacrity+vim+tmux had (and there is a famous gist for). All which is to say I didn’t have to dive deep to migrate.
