Kotlin fixes some of Java issues but it still can't fix JVM design decisions such as lack of value types (coming to JVM in what 5 years from now ?) and messy native interop. Java has some really fancy JIT compilers designed for servers but .NET is much more AoT/native interop friendly with value types and reified generics, you can get a lot closer to C++ like code with C# than with Java (avoiding GC with structs, controlling memory layouts in collections, etc.)
