Ask HN: Relative Pro/Con of These Functional Languages

I'm trying to get a relative assessment of both the functional and practical* nature for the following languages:

- Erlang/Elixir

- F#

- Scala

- Clojure

- Haskell

- Elm

Are there others you'd like to mention?

I don't expect a singular "best" list, more a "best for". The context would be for a general distributed tech stack.

* "practical" means actual use regardless of functional capacity.
