elisp is not such a great language, so the value of editing using a pile of it is mixed. It boils down to a matter of taste. If you like elisp, it's a big win and if you don't, it's a deal-breaker.
It is a great language when run inside Emacs for doing Emacs stuff. Elisp is orders of magnitude more powerful than Vimscript on Vim. Its easy to see by the best things each community has produced on their editors.
Disclaimer: I love all 3 editors for they all have great ideas.
