I've found that for Node.JS / Golang / PHP / JavaScript it has been well worth it, my workflow feels faster, I have less time spent missing clicking around even copying a line or changing text inside quotes or braces. Things like ci" or da" make life a lot easier dealing with parenthesis. The editing capabilities just feel natural I always feel like I'm programming and not just 'thinking' I believe it just comes fluently from practice and motivation for learning it. I prefer Emacs + Evil (vim modal editing) due to ELisp and I started with Emacs first never gave VIM a chance.

I also find the packages out there are pure genius such as ace-jump (originally from vim i know..)

but don't even bother for anything .NET or Java.
