I can speak about Clojure support for Emacs a bit, but I don't know how much of this Sublime or Atom can do.

I like the cider+nrepl workflow myself. You can edit your code, reevaluate it, and test it without having to restart your JVM. As you can imagine, this really speeds up development.

Also, though I haven't quite grokked all the barfing and slurping yet, paredit has really become a huge part of my code writing and editing in Emacs for Clojure code. I am on the cusp of getting barfing and slurping working for me now ;)
