I used to use vim pretty exclusively, I've since switched to neovim. There have been a few cases where vim/nvim weren't available but regular vi was and I've used it to edit text files. I imagine there were other editors but I'm so accustom to how vi/vim/neovim does things that I can't imagine using anything else. Sometimes someone will try and convince me to use a new editor and I'll try it but generally end up switching back to nvim. Even vi compatibility mode doesn't really help because I use a bunch of plugins.
