On a single display, I think I prefer HiDPI X to Windows. But the moment there's two displays with significantly different dpi, Windows runs rings around anything on Linux. Windows is surely buggy - I have serious problems with its multi-monitor support - but it seems that its multi hi dpi only occasionally crashes Firefox and it's otherwise reasonable. With Xorg, there's no effective support for different dpi. So if you can tolerate the variation in pixel size then it's tolerable, but if they're too much it all breaks. Moreover, many apps completely ignore the dpi. For instance, Spotify which is is almost unreadably low contrast doubles down and it's unreadably small too. With Wayland, it's unusable since any seriously productive app will be shown at at least quadruple size the moment you require pixel doubling, X apps will be pixel doubled twice and Wayland native apps all seem to be toys. This seems to have been a bug that was first report years ago so I suppose they're waiting until someone rights a Wayland version of Firefox and Jetbrains and so forth. Fortunately, this motivated me to by a 4k screen which I'm happy with. It's only tolerably different than my hidpi laptop screen so I don't need to worry about X's mono-dpi-ism. But it's still incredibly frustrating.
