At least from my experience with ~15 years of mac, ~15 years of on-and-off linux and windows, macOS has remained more consistent, because the primitives are much more universal.
Take, for example copying. You can alt-drag a surprising number of things across many different apps and have them just work. Or holding alt in menus to show additional entries. Or holding shift or alt to resize items to preserve ratio on one or two sides. Or take dragging and dropping references to the current file from the proxy icon in the window top bar. Or dragging and dropping selected text as snippets. Or looking up words in the built-in dictionary.
The amount of effort the mac team invested to re-use ux interaction modes is really crazy coming from other platforms, and it extends to abstractions such as disk images. One of the things that impressed me the most was how you could clone mac volumes to usb or firewire disks, boot from them, clone volumes to compressed images and restore them - all seamlessly, without messing with disk sizes, sectors, boot records or bioses - and it would just magically work.
Granted, the story is no longer that easy with APFS and M1/M2 macs, but I still think this is a bar that no other operating system has reached.
