I wouldn't try to sell you on it. Languages are tools, so your question is like asking "can anyone sell me on why I should use a flashlight instead of a cheese grater?" I don't know, because I don't know what you're trying to do. Perhaps neither Clojure nor Lisp is appropriate. Basic sales pitch: use the right tool for the job.

For many of us, Clojure(Script) is the right tool: a balance of performance, ecosystem interoperability, expressiveness, etc. on the platform we're targeting.
