The other thing is footprint of codebase, despite almost 15 years of using C#, after only two years, I consistently write F# which is 1/3 of equivalent C# code, writing idiomatic code that any F# developers would grasp.

There are ways a C# aficionado would take to try to not be so verbose, but those solutions won't be considered idiomatic by 99% of C# developers.

At the end of the day, codebase size matters a lot.
