Living inside Emacs separates you from lots of "how everyone else does it" over time and is hard to integrate with "everything else" without TONS of work.
To avail yourself of the full power of Emacs, it demands more "difference from everything else?"
But for the Emacs fans who've had success, that work pays them back because they can bend the editor to an extremely bespoke workflow.
I'm unsure if it will work out for me long term but I can sort of see the appeal. No other tool even attempts to be what Emacs has become.
So yeah, it's different from every other approach I've tried. But there's a chance it will work for me. Jury's out, though, and I am only now realizing that I'm going to have to put more effort into hacking my workflow than with other things I've used (Kakoune, Neovim, sublime, etc)
