I definitely don't think it's black or white. If you could have the power of vim (all vim, not just the basics) within an IDE, I'm sure a lot of people would be significantly more productive than only using vim or emacs. I think part of what neovim attemps to do is bringing all vim inside IDEs. That said, I have a feeling that people believe that all vim users use the editor with no plugins or config whatsoever. There are a lot of plugins out there that, while not bringing all an IDE has to offer, provide a lot of what someone would expect from an IDE, and if that is enough, I don't see why someone couldn't be more productive in it than in an IDE.
