I recommend Haskell over Clojure, because it will really expand and bend your mind. (I take as context your asking this question.) Then, I recommend Common Lisp over Clojure, because that has a lot of things that are uncommon even decades after standardization.

(I rarely do front end work and have no preferences there beyond Unity if it is a game.)
