Possibly prettier than C and C++ still. Every time I write something and think "this could use C" and then I use C and then I remember why I was using C# for low-level implementation in the first place.

It's not as sophisticated and good of a choice as Rust, but it also offers "simpler" experience, and in my highly biased opinion pointers-based code with struct abstractions in C# are easier to reason about and compose than more rudimentary C way of doing it, and less error-prone and difficult to work with than C++. And building final product takes way less time because the tooling is so much friendlier.
