[precompute]

Yes, emacs is equally performant in GUI and TUI. And frames can be opened in both GUI and TUI on the same socket.

For me, TUI is a dealbreaker because:

- No mixed-pitch support: I use mixed-pitch fonts in org-mode buffers and in outline faces in prog-mode buffers. And fonts are just plain nicer on the GUI, and it's much better to look at.

- No SVG support: (I might be wrong about this) I have a custom modeline with SVG artifacts and the artifacts fail silently on the TUI

- Keybind conflicts: I am not used to accounting for the terminal's keybinds. Also, I use xfce4-terminal, which does not support the Hyper modifier (which I use extensively).
