For my taste, Wezterm is much more configurable: I can change key bindings, mouse bindings, make custom actions/behaviors, write the config file anyway I want if at the end it generates the needed Lua table,... And it's not gonna stop here.
The code is beautifully separated in layers, Rust is used at its best for terminal reading/interpretation..
The codebase is flexible: I could write my own frontend if I wanted or use the termwiz crate (included in the codebase) to build cli apps using the same nice layered architecture..
