Folks at Grammarly have a writeup about how they are using it, it might have more relevant information for you[1].
I would definitely consider using it again, but proper buy-in takes time, and I have simply been moving too fast since then.
I am still not a big fan of Clojure myself, but it is definitely seems easier to sell than CL. In my humble opinion, if you are already a convert the benefits of going from Clojure to CL will not be as great as the ones for going from Java to Clojure.
