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

• STL has more collection types than MFC
• Visual Studio (2008+) debugger visualizes STL much better than MFC. (AUTOEXP.DAT magic can fix that - but it is a pain! Nothing like debugging your debugger when you screw it up...)

One good thing with MFC is that there is still a large corpus of MFC code out there. Other answers talk about third-party compatibility. Don't forget third party MFC-based stuff.
