I've personally never had any problem stemming from the lower levels of the system ever since Windows 7. Whenever I've seen major bugs on Windows, it was on user space stuff like the profile corruption that breaks the start menu and metro/UAP apps in Windows 10 after the major updates which can be fixed by deleting the user and creating a new one.
Windows also has a more robust architecture where it matters, like the fact that a GPU driver crash doesn't kill the user session (windows can reload that subsystem while keeping the user session running since Vista), whereas it can either kill Xorg or just outright freeze the system on linux. A very useful way to architect the OS, although I've only experienced it on Vista and had more stable GPU drivers from 7 onward.
Software stability isn't the core point - how is the stability/instability of Windows relevant to the disadvantages of a driver ABI that changes continuously?
