It seems that QWidget always uses anti-aliased fonts, and QGLWidget uses 
bitmap fonts under a certain font size, in your example 12pt and 
smaller. I wouldn't say either is better. For my taste the optimum would 
be to use the bitmap font with 8pt, and anti-aliased fonts for 10pt and 
above. I have no idea how to adjust the threshold in Qt, I just know 
that font configurations often offer to adjust this threshold.

Best regards
