Definitely Common Lisp. Instant startup time (load all your dependencies and then dump a new SBCL compiler with ‘save-lisp-and-die’), great emacs support, a mature ecosystem, and fast. Clojure is great if you don’t care about the startup time, as it has good emacs support, and you can fall back on the JVM ecosystem. It’s the most concise of all the lisps I have tried, but also a tad opinionated.
