I never got too into emacs despite learning both Clojure and Elixir in the past, but it hasn't ever been a huge issue. It may depend on how you set up your project. If you are using Clojure on the JVM, then I might recommend Cursive for IntelliJ. Generally, though, since Clojure is not statically typed, you can move between editors pretty effortlessly and use basic go-to-def tools to achieve similar experiences. When I was using Cursive, I had a sizeable amount of work in Java as well, so they all lived happily in IntelliJ.
If I were to start with ClojureScript/Clojure only codebase, I would look into "Parinfer" plugins for your editor of choice. Parinfer started as emacs only, but it gained a lot of attention and has some equivalent ported to most editors at this point!
