Windows or Mac?

MacOS is generally better designed in my opinion, and looks more aesthetically pleasing to the eye than modern Windows (not that I hate Windows 10's UI). It also seems to be more stable than Windows in some cases. The inbuilt applications and Apple's productivity tools are also great compared to the mediocre offerings that Microsoft has to offer. However, if you are a gamer, you'd use Windows, because far more support and the fact MacOS cannot be legally used on anything other than Apple's hardware. What seems like MacOS's biggest downfall (the legality of Hackintoshes) is actually a positive somewhat - since it means that the operating system is optimised for the hardware it is supposed to run on.

I'd go for MacOS as a non-PC gamer.
