My experience with font rendering on Linux is that it's much better than on Windows, on comparable displays. I have fought with my Windows station at work to get acceptable font rendering for anything but the optimized-for-ClearType system fonts, but font rendering on Linux is great, and if you have different preferences, there are adequate levers to adjust it (via, e.g., GNOME Tweak Tool).

(In particular, I get color banding and inconsistent weights in Windows, especially with thin fonts.)
