Why do people always assume that console games are more stable than PC games? The difference is that console programmers know the hardware that they're targetting, and there tends to be fewer virus and other malicious programs running on a console. That said, a properly set up gaming PC will blow any console you care to name out of the water, anyway you want to measure it.
Having said that, a properly set up gaming PC will probably cost 6 times as much as a console, but what the hey.
For mine, I'll take PC gaming over a console any day of the week.
