Well, there's always debates whether PC's or consoles are better. I've put together a comparison list, so you can decide for yourselves.

PC Advantages:

• Can have better graphics than any current console. (PC's are the reason consoles exist)
• Much more powerful. (Core i7 and 8 gigs of DDR3 RAM, anyone?)
• Is the best at many game genres, like FPS, RTS, and of course, MMO.
• Can do a lot more than just play games.
• Customizable, and very upgradeable.
• Has some great exclusive games.
• Can mod games.
• Online is mostly free.
• Can be portable (laptops).
• Mouse and keyboard controls are often superior to gamepads.
• Easy for developers to patch games.
• Digital distribution!
• Games often have very deep gameplay and keep you occupied longer.

Console Advantages:

• Very popular.
• A LOT of games.
• Have a lot of exclusive games of their own.
• No worries about hardware requirements.
• Cheap(er)
• You aren't confined to your deak.
• Party games! (Rock Band!)

PC Disadvantages:

• Can be VERY expensive.
• Technology gets outdated fairly quickly.
• The big one: Piracy and DRM.
• PC versions of most big games are almost always delayed, and often the PC version is poor quality.
• Viruses and Spyware.
• Can have hardware problems (Like melting your CPU from Overclocking to 4.0 GHz)

Console Disadvantages:

• Hardware problems (Red Ring of Death)
• Games cost more.
• Game genres sometimes don't go well on consoles (RTS, for example).
• You can't do as much stuff as you could on a PC.
•  A lot more crap games come out on consoles, such as the stuff on the Wii.
• Online services can cost money (Xbox Live).
• Can't upgrade the hardware. You have to wait several years for the next generation to come out.
• Games are often short and sometimes forgettable.

I like PC, but that's my opinion. With all this info, which do you like better?
