To clarify, I meant not just the UI itself being pretty, but also reaction speeds. IOS is still smoother than any Android distro I've touched and macOS, while sometimes lacking in the UI department, does nearly everything better than Windows. It doesn't do many things better than my Gentoo install with KDE Plasma, but that's hardly something for the common user who doesn't need all the customization and wants a smooth system straight out of the box.
