Emacs 26.3
I recently tried to seriously use Emacs over my usual Vim. Mainly because I've got so used to the GNU readline emacs shortcuts in the terminal and quite like the idea of not having to switch between command and insert mode, but damn after looking into some configuration options it really is a massively complicated piece of software, I mean not to start using it, it's probably easier than Vim but just looking at all the various modes, plugins, the whole ecosystem behind it. Even emacs lisp doesn't put me off, with some albeit minor exposure to Scheme and Clojure in the past. Especially now that I have got comfortable with Vim having no plugins but knowing enough Vimscript to be productive, I really don't think I'll switch, it's too much of a commitment.
