I’m sure there are more differences; nvim has plugins written in every language. One reason I stepped away from it is because, for development, I was using a fair number of plugins, and i noticed the starting nvim would launch nodejs, a Python runtime, a Java VM, Lua runtimes… I started to feel as if I might as well be using emacs.

So, yes: you’re right. NeoVim has more features than plain vim, including a dozen different plugin managers and the ability to write plugins in almost any language. I meant that, from an editing modality, they’re very similar.
