Haskell and Lisps (including clojure) is more an academic exercise.

Yeah, I'm sure having to guess the precise combination of tabs, spaces and newlines to get it to compile is real productive, I'll stick to my simple, well defined brackets

Neither Python nor Javascript count as "functional languages", even if they have some FP features.

JavaScript aka ECMAScript is basically Scheme with C syntax.
Python consists mostly of FP features, but it is multi-paradigm (as is most of the other languages on my list as well). You can program object-oriented in Common Lisp if you want.
I want to remind you that OP asked what functional language would be the most productive one, NOT which one would be the most pure.

I really like Elixir if you're ok with dynamic typing. It's built on the Erlang VM with Ruby-ish syntax.
