What does "worse" mean? Most people who see "worse" are actually complaining
about fonts, and in most cases even then they don't define what is "worse"
about the fonts. Can you upload screenshots of both so people can see what
"worse" means?

That said, Fedora sets some system wide variables that affect X
quality/behavior in /etc/X11/Xresources:

Xft.dpi
Xft.hintstyle
Xft.hinting

openSUSE doesn't do that. If you comment those away in Fedora, or match the
Xft.dpi number to your LCD's actual DPI, you may find the difference is
reduced or disappears, particularly if actual DPI varies more than nominally
from the Xft.dpi setting. OTOH, they may produce little or no improvement if
you've set your DTE to force DPI or tweaked its font smoothing settings.

If you need to comment further, also specify which DTE you use, as that can
matter as well in future responses.

I highly doubt it, other than if it's wrong there's no picture to assess the
quality of.
