Yep 😉

what are the main benefits of using inf-clojure over inferior-lisp?

(besides not having to set up your own keybindings) 🙂

to answer my own question, inf-clojure has a lot of clojure specific commands that send some code to the REPL behind the scenese, like macroexpand-1 or doc, so it mimics some of CIDER's capabilities

Is not having to setup your own keybindings really a benefit to most emacs users? 😉
