OSX is not superior to Windows 10. Perhaps it's equal, but it's not better. An operating system is just something to boot up and get out of the way anyway, let the user get to his apps. There is nothing great about OSX, and what you'd call a "feature" of the operating system is really just an app with a Windows equivalent.
Therein lies the problem. Win10 does not get out of the way as it's the other way. It's always in your faceless. Countless Win updates, running virus scanners, running malware scanners, etc, all before you can get any real work done. Then Win10 sends all your private data to Microsoft so yes it's secure too.
The litmus test with Windows is whether you'd log into your bank accounts from it. If you do then you do not care about your financial security.

Sure it doesn't have the app compatibility of Windows, but I only need 1 or 2 Windows-exclusive apps ever which I can easily run natively via Parallels.
Exactly this. Windows should only be used to run point apps under VM control that you are required to for whatever reason, preferably with networking disabled, as it is not something you can trust.
