I was more thinking of how many(?) people will readily use a only slightly customized vim - and be reasonable productive in a standard config, vs emacs where the stronger trend seems to be building an ide on top of emacs - to the point were to users can't readily use each other's setup efficiently - or indeed use the standard distribution without customization.
I would have thought fish=emacs and zsh=vim in this analogy, since fish isn't really compatible with bash but zsh is?
