I use Midnight Commander, Mutt and Emacs. All TUI, still. Highest efficiency if you don't mind the up front investment in learning the interface.
GUI is good for sales to status-seeking consumers, CLI for scripting. They all have their place...

nostr:npub1etqwgv34spk6p98s0pa9kp8zntgyevdrcl49eas7mswr8pe5pq4sfj8ues is an emacs fan, I think.
Followed :-p
