either or, Clojure has more of a focus on functional programming and immutability than some other lisp implementations but honestly they don't really get in the way and most lisp lean that way anyways. Personally I would say stick to Clojure or CL as there is a wealth of information and libs available for those two. Others will differ but once you know one it's a matter of style and conventions to adopt a different implementation (until you get under the hood)
