I have a hackintosh. I make my own power. For less.
You can get the same thing on Windows with something like Acronis True Image. Clone your drive, then if you have to redo the OS for any reason, clone it back. As long as it’s the same hardware, you’re golden. Thankfully though OS X doesn’t care about hardware. You can clone almost any working Mac these days and boot another Mac with the same drive since a properly done update (i.e. combo updater vs. delta updates) installs everything, including the kitchen sink.
That and Carbon Copy Cloner just bloody rocks. Time Machine, however, sucks for a lot of reasons, not the least of which is that the snapshots get corrupted after a while.
I’m extra cautious though. I have clover on a USB stick w/ the OS installer in case of need to emergency boot from it due to hosed internal drive, and I have a clone of my OS regularly updated on my data drive (also internal) that’s ready to clone back at a moment’s notice, plus an offline clone to my 10 TB backup drive.
Yay for not taking chances! 
Newsflash: OS X is not immune to indecent websites. And the OS X ransomware is just as insidious as Windows’ ransomware is.
Infinite reboots due to a broken update > reboot to previous snapshot > update to broken update again > rinse and repeat says hi!
Yes, Windows 10 has that problem sometimes. The only time there’s a broken update and it doesn’t have that problem is when you’ve disabled the Windows Update service via Administration Tools. Of course, if you have Windows Home, you’re screwed. OEM machines FTL.
More “Mac” users dual boot than you think. And a growing number of us hackintosh because we know Apple’s hardware is utter crap. My 9900k rig would eat the iMac with the same CPU alive, reguritate it, and piss all over it, all while not thermally throttling due to lack of heat dissipation capability.
Building for overkill FTW.
This one I’m pretty sure everyone can agree on. Except that guy. You know, the one that can’t even agree with himself or herself. 
You’re conveniently leaving out the part where CASC fragmentation over time necessitates deleting /data and reinstalling to get an unfragmented install back. And when you add in APFS’ own metadata fragmentation, it drives SSD/NVMe speed down. Significantly. When an OS itself brings down NVMe drives to ~700 MB/sec instead of 2-2.5 GB/sec, there’s a performance problem. And unlike with CASC, you can’t simply nuke one part of the OS and reinstall it. To fix it requires either a reinstall/migration assistant, or a clone > format internal drive > reclone so that metadata is clustered again, but that only solves the OS side, not the data side whose multiple metadata nodes still exist.
Apple leans on NAND based media with APFS. The spinning drive problem shows just how sloppy it really is. No other OS filesystem is that horrible on any type of drive. Well, unless you attempt to put it on a magneto-optical (MO) disc. But that’s on the person doing that. 
That can happen to any vendor. Apple has had some pretty spectacular failures due to faulty parts and/or batteries over the years. So has Sony. Stuff happens. That’s what replacement part stocks are for.
