These days, things are a bit different. Vim and Neovim are more easily customized, and have gained a following because it is more finger friendly (even if it is harder to learn).
Anyways, my only customizations are usually to turn on line numbers and syntax highlighting... I also have sublime, but sometimes I find writing a script it can be helpful to just use a very simple editor, write out some psudocode with comments, then slowly build it out... it's easy to get distracted in a full blown IDE. (And I'd argue emacs or vim when heavily customized effectively become an IDE)
I agree that heavily customized, emacs and vim can be an IDE and that it can be distracting. It is possible to pick and choose the desirable (e.g. non-distracting) elements of an IDE when configuring either editor, but that in itself turns into a distraction.
