It depends.
If you want to game, work with demanding programs for your hardware the way to go is PC.
If you just use you computer to browse the Internet or working that is not too demanding for thr hardware go for a MAC. (If you have the money

)
I Only used Computer with Windows (or Linux for a Netbook) and I'm overall satisfied of the product. With PC you always find one that suits your needs for an abordable price. It's also much more flexible for components that are inside and the prices are resesonable.
You canot find a new MAC under 999 $ And that's sad beacause i like the design of the Apple products. But it's really expensive when you see the price of the pieces that are inside the beast...
With a PC you can build your own and there are PCs for everybody, and every uses.
MAC are really for "wealthy" people that have no other use of a computer than personal use.
Then it's just for you to choose what you want. (But PC is what you need)
