I'd say I have the opposite experience: I've had to use the Windows Desktop for extended periods before, and found it, as you put it, "completely backwards way of doing just about everything I want to do with a computer". I even went through all sorts of lengths to "fix" it with alternative WMs, launchers, etc, but as no matter how much I tinkered with it, I couldn't even get fairly "vanilla" features (eg multidesktop support) sufficiently working without constant papercuts and limitations. Of course, things may have improved since I last used it, so I'm sure Windows Desktop circa 2020 has much improved, but a few years back it seemed very broken.
Ultimately, it's just preference, and what workflows you grow used to.
