I guess it is just a matter of taste. Clojure is the reason I have been writing software and it helped me to achieve things that would be very difficult without. It just has the right set of tools for a guy like me with systems engineering background. I find it much more understandable to use map + reduce than for loops, async instead of fork + threading code. The out of the box performance of JVM is also one reason I keep using Clojure.
