Don't let anyone make you feel you're wrong in thinking that way. I'm been using Windows for decades, I can chronical the relative rubustness of Windows with extensive use of Win95 through Win10 (but skipping the trainwrecks of ME, VISTA, and barely glancing at Win8 in horror before going from 7 to 10). Plus I'm a Mac user since th "first 100 days"—I'm a software developer for both platforms.
Windows 10 is quite good, I have no problem with people saying it's a no brainer (in their view), especially for targetted workflows (say, video workstation, 3D, audio), if not for someone with a wide variety of use cases. But the road has been rocky (usable Windows versions, for instance: XP Pro, 7, 10—that spans a couple of decades, yet note ho many version I've left out in between, any of which you were probably hating your computing life if you chose to upgrade along the way). Not every Mac OS upgrade has been seemless, but it sure seems that way by comparision to Windows, some of which were such horrors that Microsoft simply dropped current OS names (like "Vista") and developed basically from scratch for the next one—and taken years beyond their initial target release dates along the way (including Win10, which axed features and added years before completion).
But even if you say, "Windows 10 is modern, efficient, and I'm sure they've finally got it right and the next versions will simply build on this awesomeness, I'll bet on it", the fact is they are more of a pain to maintain. IBM, the original PC maker, figured this out a few years ago—it was cheaper to buy more expensive Macs than to pay for the increased IT support Windows machine required:

Again, I use a Windows 10 machine all day long. I have for years, and, coincidentally, I work for huge PC maker who does not allow us to use Macs—I'm waiting for my new Mac Pro order though, because on my own time I want to be away from windows.
But for some other viewpoints, yes, I certainly get it. If I lived mainly in a app or two I really liked, that required a lot of performance at an affordable price (say, a lot of video editing), a purpose-built Windows machine makes a lot of sense and a Mac looks absurd. Or if you're very used to solving Windows issues and don't mind some of the annoying things about Windows that bother guys like me, great, you saved yourself a lot of money by going generic.
