After spending 50 months with Clojure, I can safely say it's my favorite server-side programming language (with Datomic as my favorite database), and the tooling (CIDER + Paredit + Emacs) is really downright amazing in terms of productivity.
Then finally there's emacs which I really don't want to get started with.
For JVM development, I only bother with NREPL because vim-fireplace needs it. For library development, `lein repl` gets the job done. For application development, I copy/paste around just enough code to launch an nrepl server and run the Clojure jar directly with a vendored directory of jar files. No other tools needed really.

(and, yes, I have tried spacemacs, but found it unpleasant)
Still, the two screenshots there (of my Emacs config) may help convince you to give Emacs a try.
