PS2 was alright. PS3 was for super fanboys.
Xbox's only real problem was the whole failure rate thing, otherwise it probably doesn't make a huge difference. People try to say PS3 has better graphics, they're the same, sometimes better on the 360, sometimes.
To each his own.
From what I hear from people that have played on both consoles, it plays better on the 360, but the server problems are lesser on the PS3 at the moment.
And PC is just full of hackers.
