Why STL containers are preferred over MFC containers?

Question

Previously, I used to use MFC collection classes such CArray and CMap. After a while I switched to STL containers and have been using them for a while.

Answer 1

Because a library that uses iterators to combine sequences of any kind with algorithms so that A) all sensible permutations are possible and B) it's universally extensible, is (when you think about your concept of a container library as it was 15 years ago) such a mind-blowingly marvelous idea, that it has pretty much blown out of the water everything else within less than a decade?

Seriously, the STL has its flaws (why not ranges instead of iterators? and that erase-remove idiom is not exactly pretty), but it's based on a brilliant idea and there's very good reasons we don't need to learn a new container/algorithms library every time we start at a new job.
