PC. Apple controls everything about Macs. They can only run on certain hardware, and the software compatibility is absolutely pathetic, especially with games. This system prevents progress--look at Steam. The same games play much better on Windows on a Mac computer than they do on Mac OSX on the same computer due to the tight control of drivers. If I wanted someone else to do everything for me and tell me what's best for my computing needs, I'd choose Apple, but I prefer control in both hardware and software. Thus, Windows and Linux are my favorite OS's.
