I write C# and Python, and C# is much more expressive than Python is and performs about 10x to 77x better. C# has much better pattern matching and has operators to deal with null and support for it in the type system. C# records can be serialized without issue (Python's built in JSON serializer can only serialize dictionaries). Althoigh variable scoping in C# isn't perfect (object patterns in if statements pollute the outer scope) variables at least aren't just function scoped like in Python. You can define user defined primitve types in C# which enables bettrr support for domain typing than what is possible in Python.
