Have been using it professionally for a little bit now. -RAII -Smart Pointers -Classes(or not, your choice) -Lambda Expressions -Amazing Standard Library -Lightning fast -A compiler that you can trust -Static types -Templates -Well defined semantics for pointers, references AND values. -Moving semantics.

And this is the "Vanilla" version of the features. In C++17 and C++20, there is all kinds of goodies like concepts and modules that I'm personally excited about.

Hate it all you want, but it's an amazing language.
