While I see XBL has some nice features on top of PSN, they don't appeal that much to me... I'm a old gamer, I don't play with friends in game parties anymore, I mostly play alone, or online with people I don't know.
So I don't see why I would pay for cross game voice chat or a party system I don't use. PSN is more appealing for me.
But I can definitely see why those features matter so much for some.
