F# exceeds C#'s capabilities in essentially every way. The only time C# does much better is when you need the VS drag n drop GUI tools. Some folks also feel more comfortable doing certain types of very imperative code in C#. Other than that, sometimes there are problems with libraries that specifically target the C# compiler's exact output. Examples are functions that take an object, then dynamically look at the property names instead of just using a dictionary (F# can do this, just isn't a major focus like in C#). Or poorly written expression tree code that only works with C#'s output. That said, the F# community can often find a fix. Once you adjust to writing so much less code, it's very hard to enjoy writing C#.
