There's one huge difference between Haskell and PureScript: strictness. PureScript is strict, whereas Haskell is lazy. So be careful when you write algorithms which rely on laziness.
PureScript is pretty much haskell, it simply compiles to javascript -- wouldn't say there is much skill transferability in terms of language when coming from js, but it might make sense if you develop front-end.
Don't know about the other languages.
