I think you should start a survey, not ask a question.
A few years ago, I used MFC a couple of times, until I stumbled upon WTL (in 2002 or 2003). I started to use WTL exclusively, and never looked back. In those early days, WTL looked much better (e.g., icons in the menus), and performed much faster.
If you look in the WTL section of CP
http://www.codeproject.com/KB/wtl/[
^], you'll find a lot of examples.
In the last couple of years, if I have to do a quick UI, I use Winforms. I don't know exactly when or how it happened, but I find development easier, and performance still reasonable (with a dual-core or better machine).
Just my two bits,
Pablo.
