Pros and Cons of different string types in C++ -

O.A. But sorry to start those unnecessary questions, but I am just curious for everyone's professionals and opposition. Different string types in C ++ are my special question between MFC's CSTRings and std :: String (since I just I am doing Windows software), but it will expand in any string format in C ++, why you are typing the best string in C ++ Not and why?

Update: I actually got a duplicate question. For those who have already responded, please direct any new responses to this other question:

When in Rome in Rome, do so. If you are using MFC, then use CSTIR because class all are optimized for it, use std :: string, as it is standard and you will find the experience useful in other references.
