I used Emacs Live for quite some time. Then tried https://github.com/bbatsov/prelude because I couldn't get Emacs Live work with the most recent CIDER (clojure environment). I have been using that ever since.
If you check out the most recent release (as of 40 mins ago) you should see that Emacs Live now includes the most recent CIDER. You just need to include the following in your ~/.lein/profiles.clj
I'll be another voice for prelude. It really is a nearly-perfect emacs setup (other than guru-mode, which I find annoying, and having to set up a few projectile/helm related things by hand). I've grown to love the zenburn theme, too — it's extremely relaxing on the eyes.
I highly recommend prelude to anyone who's not coming from vim (for them, I recommend spacemacs).
I'm also a huge prelude fan. Very easy to get helm, projectile, and cider working. I've used spacemacs (love the theme), emacs live (love the theme), Steve Purecell's emacs config, emacs starter kit, and others.
I settled on prelude because it is the most like a "vanilla" emacs installation (unlike spacemacs), and is easily extensible.
That's unfortunate that CIDER doesn't behave with it. I was curious about this because I'm currently using my own tweaked version of the Brave Clojure config, and it's woefully out of date and attempting to update it just broke everything.
