The PC is by far the best gaming system. However, I will argue that a true gamer has all current consoles and a PC. A true gamer will also buy a game for whichever system it plays the best on. PC's have the widest variety of games available and cater to any kind of controller imaginable. You can use the keyboard/mouse for RPG,FPS,RTS and Adventure games. There is also a wider variety of controller manufactuers for game pads, joysticks, and steering wheel/pedals.

I have been updating and adding new content to my games for my PC since Doom. I probably played Doom for a few years via a modem; with friends. I can't begin to count how many maps I downloaded, its well over 500! You couldn't do that with a console until the Xbox.

The PC gets my vote mainly for the replay value of most of the games you can get.
