I have used both Sony and Microsoft consoles for years now. Been a hardcore gamer for over 15 years now and over that period of time this is what I have learnt.

THE best console for an individual is this... Buy what YOUR friends will be buying. These consoles are designed around social networking with your REAL-LIFE friends or friends you make over games.

It sounds silly and simple but unless you plan on playing this by yourself then the choice for me is based on the Unique titles for each console. Work out what sort of game you enjoy and find what the exclusives are for that console and enjoy.
