I second this. WezTerm is very fast (much faster than anything libvterm-based), very featureful (comparable to Kitty), and very configurable (comparable to Vim, if not Emacs itself). Showing fonts the way I like (and not he way macOS defaults to): check. Sending complex key combos as custom sequences: check. Palettes, mouse support, system clipboard support: all check. Selection and search mode: check. Linux, MacOS, and even Windows support: all check!

I wish Ghostty all the luck, because the current state of terminal emulators is a pretty high bar to clear.
