>has any Vim user actually seen real world benefit after switching to NeoVim I've tried NeoVim for a couple of month this year. It's a tad snappier than vim, but there are a number of "quirks" (behaves ok, but doesn't behave exactly like vim) that made me walk away from it: at this point, vim is so hard-wired in my brain that any tiny difference in behavior is painful.
What for example? I genuinely haven't noticed any difference out of the box. I usually also don't like deviations, hence why I can't stand Emacs' Evil mode.
I still use Neovim, but this is my main gripe. Broadly I like it a lot, for reasons others have covered.
