So many apps on Windows, you might get the latest font rendering stack, you might get the old one, even in Windows' own settings UI

I am probably an edge case as I use a tiling WM on linux, there is little UI to be scaled. The only metric I am worried about is max text at my personally readable size. I could change the font sizes on a 4k monitor, but websites are the only non-text UI I interact with and they don't care about your OS settings. Zooming is hit or miss on if it breaks the layout or not. I don't doubt MacOS would be better in general, but for me a QHD 32" is plug and play, most websites work well and no settings faff or zooming.

Wayland implements the exact same supersampling based scaling that macOS has, Wayland scaling is even better performing than macOS'

it doesn't work great, elements are comically too big on 32" 4K or just too big on 27" 4K, you need to scale it to 1080p but then it's too small. MacOS is made for 5K 27" monitors for high DPI (Retina) resolutions or non-high DPI 27" 2560x1440. The only high-DPI 4K screen that works great OOB is the 21.5" 4K Apple display.

Too bad MacOS looks like dog shit on a lot of regular-ass monitors.
