"Technically superior in isolation" argument, unfortunately (as relatively short history of our field shows) rarely manifests in tools being actively used by many. Coalton's type system is absolutely more powerful than what Clojure offers. But language choice in production is dominated by libs, hiring, tooling, and operational maturity - Clojure wins all of those handily. Unfortunately, the same argument can be made about Clojure and... I dunno, Python. Clojure occupies a middle, nicely defensible ground.

SBCL is a fine choice for a solo project or research; recommending it over Clojure for a team/production setting though requires ignoring most of what actually matters. Every language stack choice is a bet on where the tradeoff between power and pragmatism pays off for your specific context. Clojure's bet is a more conservative than CLs, yet both may seem (for some) more aggressive bets than just using Python. It all depends on the team.
