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

It is now assumed that C++ developers are at least passingly familiar with the STL. Not so for MFC containers. So if you're adding a new developer to your team, you will have an easier time finding one who know STL than the MFC containers, and thus will be able to contribute immediately.
