Your take on desktop Linux is quite accurate, but Windows feels less QA'd than Linux to me nowadays. Windows will give me a popup begging for a reboot, then when I reboot it asks for another reboot. For months there was a bug where the settings window would become tiny and resizing didn't work. The Microsoft Teams "get started" window takes on the order of 30 seconds to close - that is I click the X button, no immediate reaction, and then it closes half a minute later.
