I've evaluated both (and also lumen) briefly. I disliked the half-way approach that doesn't isolate Lua's messy state handling from lisp model. Clojure also interacts with Java, but it feels like CLojure is the host that runs Java methods as needed. The separation is clean and you know exactly when you are crossing the boundary into stateful territory. I see the value of those languages for lispers wanting to script the platforms where Lua can run, but not really as a core language for modelling your domain.
