Personally, I find https://github.com/Gozala/wisp to be a whole lot more coherent and readable (and probably more mature, too, even though it has much less documentation).

wisp also generates very nice JS code (and source maps), and my only real problem with it is that it lacks the time and resources ClojureScript clearly commands at this point.

(edited to add: wisp also has a fair amount of activity: https://gitter.im/Gozala/wisp)
