Is it just me or fonts really look better on GNOME and other (gtk DEs)? With the same font smoothing/anti-aliasing settings, text in GNOME is smoother and more similar to MacOS fonts.
A good example is Cantrell font. It looks way better in GNOME than in KDE.
Choose a font and size, then do screenshots of the same word on kde and gnome. Then open gimp, put each screenshot in a layer, align them and make it show the difference. Then you objectively know if and how they’re different
