The main feature for me is splitting panes. I used to that in tilix and got western working exactly the same (can't stand tmux , sorry).
The Lua configuration is very intuitive as well.
I do get some indirect crashes when Xwayland crashes, which is rare. I had to disable Wayland support in wezterm because the window decorations aren't great yet.
I'm with you! tmux is pretty much a non-starter for me beyond a remote job manager.
My window manager (Sway) already requires enough wild incantations. If any, I really appreciate simple integration in the terminal.
A little more than 'foot' but not a lot. Tabs/panes, like you say. It gives some more granularity to the organization without a lot of new buttons to push.
I've taken most of the Tilix defaults through several! Currently Kitty... though I may try WezTerm.
