Consoles: Gaming with friends offline is best.
PC: Everything else (for me at least)
Since i dont have friends (Forever alone) i play PC.
Only downfall to PC: maintenance, you need to learn some stuff to get some games to work, while in consoles, its go go go!.
So if you are pacient, and like to get things done just right, PC is a great option.
If you are a casual gamer, that dosent have much time to lok around and waste on getting the PC to work perfectly, id say console.
Finally, if i was going console myself, id wait now for the next generation.
Getting xbox or ps now seems like a waste for me.
