Hands down PC. The main reason is because I prefer to build and maintain my own devices. My home pc is primarily used for gaming, photo and video editing. As I build my own, I can pick the specifications that I want, not what somebody tells me that I need. Windows is also a far better platform for gaming (Apple runs games notoriously poorly for what should be a similar machine). For example in the game that I'm playing, the latest Macbooks struggle, where a similarly priced Windows based laptop runs it with no issues. By building my own PC, I also saved about 70% of the cost of a similarly specced Mac, not to mention have the ability to upgrade and replace parts as necessary. I have a couple recent things that have solidified this.
I have a power PC that I built for myself in February this year. The hardware equivalent is a Mac Pro Quad core. I have the same CPU, more ram, similar video, bigger SSD, a HD which the Mac pro does not have and I can swap out equipment at any time. The price of the Mac Pro? $3200. The price I paid? $1300.00
The second story is with regards to my parents pc. They were having perceived performance issues with their desktop pc. I went over and found that the hard drive wasn't performing well. I bought a new SSD, installed that and they are very happy with the upgrade. With a Mac, you cannot perform upgrades like this, so they would have had to purchase a new computer for $1000+ instead of a $100 upgrade.
There are definitely times and places for a Mac, however for typical use at home, and those that know nothing or want to know nothing about their hardware can do nicely with them, however those that do know a little bit about hardware, the quality of their hardware and want good value for their performance, the PC is the better bet. It all depends on you.
