Since there are counter-anecdotes, I'll throw in my supporting anecdote: I've had endless problems with multi-monitor on Windows 10. Especially if they're different display densities. Windows that go out of bounds and are un-retrievable, permanently glitched window-content rendering when moving between densities, inaccurate mouse positions, desktops that resize to like 320x200 and then to the actual (shrinking every window and mashing all icons together, and breaking the notification area and status bar area in the process), I don't think I've ever had it work out-of-the-box even once on multiple machines and multiple monitors / projectors / etc. Some of this only occurs the first time it learns a new setup, but much of it just keeps happening randomly. On macs for like the past 5+ years? Almost perfect behavior, for almost every OS version, except on apps that clearly do their own thing (e.g. IntelliJ sometimes shrinks to nothingness, and Steam is just hot garbage much of the time).
