Can't read the article, but I use evil every day to do my work. I don't like vim so much as I like modal editing, and evil gets it right for about 98% of what I want. Emacs is (IMO) just a better platform, although going down the road of learning emacs, but none of its bindings is pretty rough, and probably a bit too much work for most people (m-x describe-key was my greatest friend when going through that process)
