I think you might need to reword that. By simply having a lens with a fixed aperture does not automatically give you better quality.

All the fixed aperture lenses will do vs a floating aperture lens is the fact you will lose x amounts of stops worth of light. It will help yield a faster shutter speed but still can result in bad IQ.
