I personally believe PC gaming is superior to console gaming. Generally you can get PC games for a cheaper price, and the PC gaming community (Steam, Desura etc.) is very supportive of the growing independent game scene. A PC has a very long shelf life when it comes to gaming, if you are willing to upgrade things like RAM and a video card every few years.
Console gaming is far better than computer gaming. The reason is the ability to play with friends without networking. For this desire there is something in computer gaming called a lan party, in which a group of people get together, and set up their machines and connect to one another to form a local area network, in order to game together. With a console, all can play from a single device, thus no extra setup is necessary for a group of friends to get together and play.
