The main reason I like vi/vim is that if you’re having to use multiple different computers (such as if one is a sysadmin, or in my case, does scientific computing), because if you’re running on Linux, you can be confident that vi/vim will be on it.
For personal use, I’ve been using emacs, but I can’t recommend that without feeling like I’m suggesting you try some heroin. I enjoy emacs because of it’s complexity and how much power it gives me to modify it. It’s very easy to fall into feature creep and over complexity though. That’s why I can’t recommend it — it’s good for me because I am a chronic tinkerer, and having something to fuck around with is an outlet for that.
I would recommend learning the basics of vim though. As you highlight, getting back to your current level of productivity would take a while, even if you loved vim and committed to it wholeheartedly. It is possible to try it out with little commitment though, for the perspective. If you’re on a machine that has vim installed already, try the vimtutor command, which will start the ~30 min long inbuilt tutorial for vim. I liked it for giving me perspective on what on earth vim even was.
I know you don’t use it anymore, but I just want to fistbump you re: sublime text. I really loved that as a basic text editor that was, for me, just a slightly nicer notepad.
It would be great if you could avoid using ableist slurs to refer to people you don’t like
