That's overly prescriptive in terms of what users want. In my experience users who are used to macOS don't mind slightly blurred text. And users who are traditionalists and perhaps Windows users prefer crisper text at the expense of some height mismatches. It's all very subjective.

It always makes me laugh when apple users say "oh it's become of the great text rendering!"
The last time text rendering was any good on MacOS was on MacOS 9, since then it's been a blurry mess.
That said, googling for "MacOS blurry text" yields pages and pages and pages of people complaining so I am not sure it is that subjective, simply that some people don't even know how good-looking text can look even on a large 1080p monitor
