My system is one I custom built myself. I don't really think I've ever owned an OEM desktop before. The driver issues I tend to have was with multiple USB WiFi adapters I've tried with my computer. I had to do some really weird black magic shit to get them to work properly. I also couldn't run my TV at 4K 60hz on Linux, but I could on Windows. Freesync has also given me issues when trying to activate it. Not the fault of Linux if manufacturers don't give it proper support, but this has been my experience unfortunately. Windows would indeed have more driver issues if less drivers were being officially supported like if any other OS didn't get proper driver support, so I'm not really sure what you're trying to point out to me. What exactly is "consumer grade hardware"? Doesn't Windows run on other things as well besides just your typical desktop?

I tend to have driver issues more so with Linux than windows in my experience. Both seem to be capable at the very least of automatically installing a lot of the drivers without user intervention.
