I've always used a PC, but have used a Mac occasionally for the last several years. Window management seems nonexistent on Mac. What do you do specifically that makes it work so well?
I'm thinking of things on PC like alt-tabbing, tiling windows left and right (which then allows them to be resized together so that they always fill up the screen) and grouping of windows in the same program on the task bar. On Mac I'm always just dragging windows around to get them out of the way, though I'm sure I'm doing it wrong.
I don't like snapping windows to fill up portions of the screen except in rare instances, so we might have different ideals here. But the big things for me are 1) treating individual desktops as actual individuals and 2) the use of spaces.
1) RIght now I use a MacBook that I keep closed 99% of the time with three external monitors. I can move my mouse to a specific screen and use a three finger swipe to switch between multiple desktops on each screen without changing desktops on the other screens. The last I checked, Windows 10 treats all of your screens as one giant desktop, and if you want to shift to a different virtual desktop on one display, it changes it on all of them.
2) I guess this is related to the previous item, but I can swipe three fingers up to view all of my open windows on my currently active desktops. If I move the mouse up to the top of the window on one of them, it shows all of the virtual desktops available on each display. I can then move applications from any active virtual desktop to any other virtual desktop that the system is currently using.
I mostly just find it easier to work with a bunch of open applications on macOS by virtue of using Spaces, virtual desktops, and gesture controls than I have been able to manage on the Windows side.
