I actually came to Scala via F#. You can even find exact dates of those transitions in my stackoverflow history.

Scala and F# are sinilar enough to basically be the same language, though I found F# had a number of warts and idiosyncracies that made me move on to Scala. Scala didn't have all of these (though of course it had warts of its own!) and is what stuck with me for the long term

F# has a much more primitive type system than Scala and isn't particularly impressive imo. And it doesn't have functors ala OCaml.

What I like about F# vs Scala is the ML-style syntax and the relative simplicity. I have found Scala staggeringly complex every time I have tried to learn it, it seems like the C++ of functional programming languages. This impression may be misguided.
