I recently changed from Alacritty to WezTerm due to bugs in the former and I don't have any complaints so far. It is part of my daily professional workflow, works well with Tmux, under WSL. Great piece of software.
I went in the other direction and use Zellij for multiplexing. It works well for me, and I’ll be keeping an eye out for the Ghostty public beta to see how that compares. Great to have all these good options.
