I think the standard library is good, but if you pull in ANY of it's headers you add a couple hundred milliseconds to every translation unit. So when making games (and only then), I avoid the standard library.

What I do like and use is overloading, references, templates, concepts, lambdas, enum classes, user defined literals, constexpr, operator overloading for math (!), little syntax stuff like structured binding declarations, "auto" and range based for. I also made my own little fmt (like https://riki.house/fmt). C++ is a much nicer language than C imo, even without the standard library.
