F#'s biggest issue is C#. It benefits from Visual Studio and Jetbrains Rider as best-in-class tools, but having to rely on the .NET Framework means relying on an OO first library ecosystem in your functional code. Which can be clumsy and looks a little messy with the mix of camelCase and PascalCase functions.
Also, it has support for features that probably shouldn't be in the language, but are because of C# (interfaces and type-inheritance for example).
The compiler is slower than C# but arguably fast enough. And they have made a weird choice about ordering of source-files dictating ordering of compilation, so you have to manually sort source-files in the IDE. Which is both a pain and makes it sometimes hard to visually find your source-file because they're not in alphabetical order.
I like F# but it doesn't have enough unique features over C# to make it worthwhile imho.
Disclaimer: The last time I wrote any F# was about 5 years ago. Things may be different now!
