I don't mind either, but I prefer a Mac now only because I got very comfortable using mine. Everything just loads faster, you can do multiple things at one time, and it's very user friendly.
The only good thing about macs are their moniters. Otherwise they were built for retards. I've had this PC for three years, with minimal problems, which can all be traced to new hardware.
Personally, I like Macs better
but they each have good points
Macs are more expensive, but you don't have to get anything else
PC's are cheaper, but you have to get all that security s**t
