In the surface you can say yes or no (only looking at types and such). But summing all the features, F# is far more immediately productive.
I take rust after 2 years on F# (that I continue to use). I have like 2 months of Rust now. I still struggle to solve things that are "no-brainers" in F# or swift (mainly, because Rust is VERY strict about know statically all about the code, and VERY hard to build generic, dynamic code).
So, it will look less expresive, IMHO. I still ramping-up and start to get more a more of the rust style of programming, so the pain is reduce. With the additions for rust in the near future it will reduce it more, I hope.
