What makes Fennel a bit different is that it is a Lisp inspired by Clojure. If for any reason neither of these ever interested you, then, yes, Fennel would not feel any different to you.
Like I said, if one likes Clojure but has to write for a Lua-enabled platform, Fennel is the best choice today, since there's no Clojure dialect for Lua, like ClojureScript or ClojureDart. Fennel although inspired by Clojure, still a very different language. Phil Hagelberg, AKA @technomancy, is the maintainer, a well-known and highly respected Clojurista.
