Which one should I buy ? PS3 or Xbox 360 ?

[Kantor]

As has been said several times:

-Look at the games. This is more important than anything else.
-Do you want Blu-ray?
-Can you afford to spend $400 on a console?
-Do you want free online or slightly better online for $50 a year?

Now, if the PS3 wins the first category and loses every other category (except maybe the third, but if that was the case you wouldn't be asking), you should go PS3, and vice versa.

If, however, you like both exclusive libraries equally, look at the second and fourth options and make your decision.

That was the unbiased part.

Now, the biased part: Get a PS3.
