Tonsky, the creator of the popular 'Fira Code' monospace font, has a great blog post about monitor DPI and font rendering. A big section is on just how terrible font rendering and display scaling on a modern Mac really is.
I only use the desktop mac so that's not much an issue probably, there it is probably 2x scaling. Interesting how Windows can handle anything as long as the hardware supports it!
250 sounds nice, compared to 220 retina ppi for macs. If its only constrained by the display that would be good. I will love buying 3080/5950x as my new workstation. hmm
I run Arch on a Surface Pro 7, (ironic, I know), which has a HiDPI display and the experience is good for me under GNOME, even fractional scaling is supported.
One thing to keep in mind is that Windows/Mac/Linux do render fonts differently - they may not look identical to macOS out of the box, but there's a lot of configuration options (if you want to play with them) to get them to look the way you want.
