I use both approaches. One thing is that Clojure code bases are comically hard for anyone to mentally parse if they didn't write it. At least the bulk of programmers... like you'll find on an actual team. Great to write, sure, but not useful in terms of onboarding new team members. Clojure programmers are typically great thinkers. And veterans. But if you are actually trying to build a company, then beware. Your handful of expensive brilliant programmers will build something that you can't bring people in to expand or maintain. Also watch out for the fact that the companies making the awesome tools that COULD be used by noobs often keep them closed source (Datomic and, I think here, Rama). They intend for you to hire them as consultants and pay licenses. Which is all fine... except the 2D languages have real open source libraries with huge adoption and ecosystems.
