This is a matter of taste.

Yes, using FREETYPE_PROPERTIES helps you immediately, but...

...the main culprit of the bad appearance IMHO is lack of linear

the latest Qt release (or the next one to come) supports linear
blending, so it might be worth to try it!

The main question is: How do those fonts look on Windows?  Can you
provide screenshots, pointing to differences?
