Doubling the DPI of the display makes the fuzziness less noticeable of course, but someone commented on this site that the fuzziness bothers him even on a retina display, so he distinctly prefers Windows's text rendering over Mac text rendering on the same hiDPI monitor.
As noted in other comments on this page, many Windows apps are blurry when the OS is set to a scaling factor other than 1.0, but Chrome, Firefox, the new Edge browser, Emacs, VSCode and most of the apps (e.g. Settings) that ship with Windows do not have that problem.
None of the apps except VSCode that I have opened on my Linux install over the previous 3 months are fuzzy when the OS is set to a non-integer scaling factor either, though in that case I have had to learn to adapt to certain minor bugs in Chrome and Emacs.
