The Windows desktop comes in last in any reasonable comparison with OS X and a modern desktop-oriented linux like Ubuntu or Mint.
The focus on backwards compatibility means, among other things, Windows is carrying around multiple ways to render fonts. None of them deliver sufficient clarity. In Windows 10, Cleartype does not affect "Modern" apps.
All the applications I use 90% of the time are available for Windows and Linux. Text in each is more difficult to read in Windows.
I find, on a Dell 27-inch 2560x1440 display,that I can see individual pixels in normal fonts from my usual viewing distance. Bold fonts are often smeary, especially at smaller sizes. Segoe UI looks acceptable in parts of the Windows interface. But, in apps that use older font rendering approaches, it's poor.
If you spend your days reading and writing, as I do, this is an important issue.
