It depends on what you looking for:
Price point: Windows win because it is cheaper to get a Windows PC.
Gaming: Windows win because the whole video game industry focuses on Windows and vice versa.
Creative professional works: Apple wins because the whole creative industry focuses on Apple and vice versa. You can get a cheaper Apple PC that works better compared to a Windows PC compared to this. Some may say "Windows good too" then Apple is good for gaming too because this logic has such a ratio here.
Security: Apple wins. Tons of shit uses Windows and it is very popular so more oppurtinities for hackers to exploit and wreck way more computers.
Versatility of use: Apple wins. Use Apple devices between each other way better than Windows can.
Ease of usage: Apple wins because Windows doesn't care about ease of usage. You sit in front of it and gotta fine-tune that shit to adjust it for your usage while Apple does what is common sense that Microsoft should learn. Not to mention variety of hardware in Windows computer calls for different settings, different ways of usage and different ways of troubleshooting are all very minimized on Apple.
Problems: Apple wins. In comparison Windows has always been problematic, in which only XP being a decent OS among Windows family.
Overall who wins? Of course HAL 9000 wins yo!!!:
