From my own experience...
I had been using Windows 10 on my main gaming/daily driver desktop for over a year- until earlier just this month. That system is going on 6 years old (the last upgrade was a new video card in 2013), and Win 10 ran pretty smoothly on it- better than Windows 8/8.1 on the same hardware. Through third-party utilities, I managed to get the UI more or less how I wanted it, defeated Cortana (every time she re-appeared, searchui.exe was mysteriously renamed c*ntana), made sure deferred "upgrades" was active, and so on. In all, I managed to mitigate most of what I found to be the most egregious sins and trespasses pretty well. The forced ordinary updates that actually caused some sort of problem were few and far in between, and could often easily be fixed. Many of the under-the-hood improvements in security and performance were welcome (at least relative to Win 8/8.1).
Back to earlier this month: on or about the 15th of December, when I shutdown the system (a real shutdown- I disabled quick-start or whatever it is) I was not surprised to see that the system was once again installing updates before going to bed. When I booted up the next morning, the system would appear to hard-freeze shortly after loading the desktop, and after about 5 minutes, would give me the condescending "Something has gone Wrong :(" BOSD and reboot. Of course, MS removed the traditional F5/F8 safemode startup, and it's pretty hard to tell the OS to boot into safemode by restarting it when it's locked up, so there was nothing else for it. The system was well and truly borked, and needed reloading.
At this point I very nearly decided to install one of the more consumer friendly Linux distros. I'd used Ubuntu in the past on a Compaq laptop with excellent results- I could do pretty much everything I needed with it, easily and efficiently. I fired up my ancient, trusty Wind-tunnel G4 PowerMac running OS X 10.5, and started downloading Ubuntu and Fedora's latest and greatest. Either would support a good deal of what I did on that system, except one very important caveat, and indeed my Windows system's very reson d'etre: Gaming.
Were it not for that, I would have gone ahead with my plan. However, it was a sticking issue, and I was compelled to go out to my garage in sub-freezing temperatures, climb into the loft, and dig out my Windows 7 restore discs, and begin my 5 hour odyssey of reloading the OS, downloading service packs and updates, finding that Windows Update (under Win 7) wasn't working, diagnosing, resetting, downloading updates to update the updater, changing registry settings, ad naseum. I still do not have all the programs reinstalled that I need (though I was pleased to find that, unlike under Windows 10, my copy of Adobe CS2 launched like a charm). I would have had to do similar with Linux, save for reinstalling Steam and all my games (when you only have a 4Mb/s internet connection, Fallout 4 with all the trimmings takes a week to download). That said, it did make me appreciate how "Mac-Like" Windows 10 was in that, after installation, Everything Just Worked™ (at least to the point where it didn't).
Still, I am not, at this point, keen on reverting back to Windows 10. Windows 7, at least as of now, handles everything I need without the need to "fix" it. And it gives me control over my OS (privacy, updates, etc) instead of the other way around. If Linux had broader gaming support (either internally or with software publishers), I would have ditched Windows. At the very least, if the games that I played were well supported with WINE or similar, it would have been viable. I mentioned that my other system is a vintage Mac, and while many newer games are being released for OS X, this rather excludes my old G4 system, and would require purchasing a new, expensive system.
