Has anyone had experience of both Elixir and F#?

I've dabbled with both - but really fell in love with both of them! I come from a C# background, so the static typing of F# is a big pull. OTOH, the simplicity of Elixir was an absolute delight - after just an afternoon, I felt like I had a decent grasp of it.

I'm conflicted, and would value some other opinions?

Depends on what you want to do, I think. The pros of the BEAM likely outweigh the cons of Elixir's dynamic types for distributed messaging systems, e.g., Discord. Otherwise, F# and the SAFE stack probably can serve other backend needs more safely with better library support from .NET. Elixir does seem more trendy than F#, which has lagged somewhat due to second-class support from Microsoft and lingering dislike for .NET -- hopefully things will improve as .NET Core matures.
