I still haven't really tried neovim and have just stuck with vim classic. I think it's because I can assume classic vim will be installed on any remote systems I need to work on, and this isn't true for neovim, unfortunately. I suppose if I really leaned in to learn core vi things, it wouldn't matter, but I have my vim plugins and dotfiles that are a git clone away on any system, and I guess I got lazy.
I've tried to use vim-likes in the past, specifically spacemacs with evil-mode, and ran into enough goofy problems that it scared me back to vim.
Seeing this, though, maybe I'll take the jump. For sure would be more comfortable hacking together things in Lua over vimscript or vim8script.
