Only empirical evidence. I did a fresh windows install to the (officially supported) living room PC and I have to deal with crap so often that I'll probably switch it back. Some examples: - Bluetooth stops working once in about a week and only starts working again after ~3 reboots and some luck. Reinstalled drivers and fiddled with it many times. - WiFi just stopped working altogether 3 weeks into the upgrade. It just refuses to work. Again, reinstalled (officially supported) drivers and messed with it a lot. - The fans go louder and it's generally hotter. - This may be a really weird bug that's possibly irrelevant, but the bootloader loves to erase itself from the efi boot options. If you go into the efi settings you have to manually add it, if you don't it'll work until you do. - General UI bugs (lots of them) - Subjective, but way more convoluted and annoying UI I've heard the same kinds of things from other people too. My advice is to skip upgrading for as long as you possibly can.
