I used C++ Builder years ago and I loved it too.
These days though its all MFC for work reasons. And once you get used to it, its not too bad either.
In either case, I can't say I've ever been the victim of any serious type safety problems anyway. And in the professional world, you'd be hard pressed to CYA if you ran into problems using freeware instead of MFC.
You'd be just as hard pressed to CYA using a Microsoft product.
