You pretty much answered your own question. Common Lisp is the big one. Scheme has more of a niche as an extension language, but Racket is a completely decent development environment and language family. Clojure is a JVM language with some neat persistent data structures. Personally I find it to be one of the least interesting Lisps, but that's like saying it's not my favorite pizza. It's still quite tasty. Furthermore, I can easily get paid to write it, which is a little harder for the others.
