After Emacs/Cider/whatever crashed/locked up on me for the 20th time I finally gave up and moved to Cursive over a year ago. I've never looked back, it's fast, does what I need it to, and I still discover features all the time (like the clojure.test integration!). It's also a fantastic way to get new programmers into Clojure. No need to download lein, or dozens of packages or learn a text based editor. Just install InteliJ and install a single plugin.
Great work.
