I think that PC is the best deal out there. That being said, it's the worst to dedicate all your spending to, because you don't need to spend on a card to accrue.

You can get all the properties for $350 or less. That can translate into a good deal. The 5k PB can be a good deal, and can basically lead to a free vacation. That being said, the list (like the last one) tends to be rather lame.

SPG points are maybe the most 'valuable' but their redemptions can't come as cheaply in terms of hotels.
