this topic really boils down to personal preference and needs....
Mac: great hardware based systems and well built android-like OS. Amazing picture software and editing features as well as friendly user interfaces and integration with other Apple products.
PC: you can essentially use whatever hardware you choose. Thus, great hardware options. Windows is compatible with almost any application you can think of which makes it great for almost any scenario.
I personally like Windows as I'm a Network/Systems Admin and I like using lots of different applications.
In the end, it all depends on your needs and focus. If you're a photographer/graphic person, go with a Mac. If you want to customize your computer and like tons of software, go with Windows. Or just pick which one you like better.
