True, C# is a nice language, but so is Kotlin. Java support for value types is being developed and has a dedicated JEP 401 [1]. Kotlin allows to use value types today, it also has nullable types. I'm not convinced if functional features are really a factor that decides what is popular or not; it can be attractive for hardcore programmers, but most of programmers are not that.
