We have both (including desktops, laptops, tablets and phones). Honestly, both can get the job done just fine for whatever you want to do and both work quite well.
I do find Windows offers a lot more freedom of choice and for significantly less money to accomplish the same thing. But I don't think one is necessarily better than the other, rather it's more a case of what one prefers.
Then again, I never had a problem with VISTA, Windows 8, or Windows 10 either.
Insofar as a multi-monitor environment, I run a 4 monitor display on Windows 10 with absolute ease of setup. Not this specific one, but a similar setup nonetheless. I'm using a higher quality ATI card with EyeFinity and a Windows 10 machine. It is awfully easy to set up.

I'm not sure what you're having problems with Mark... but setting up a multi-monitor display in Windows is ridiculously easy. Perhaps you're just so used to MAC removing your input from the setup process?
