In my experience with Windows 10, it depends on the app. A lot of apps are blurry. Even some of the ones shipped with the OS, made by Microsoft, not to mention third-party apps. Linux with KDE works better than Windows here[1].
I've also read the opposite opinion about macOS - namely, that it's the platform that does it best. I've ordered my first Mac (mini). It's arriving in 2 weeks. Will see then.
Overall, poor HiDPI support on Windows is one of the main reasons why I decided that I don't want to switch to Windows as my main driver and instead try macOS.
[1]: GNOME on the other hand is terrible. It's possible to get i3 to work with HiDPI, but there's no end to the work you need to perform to do that.
