This is turning into a 'which is the cheapest console' argument, so it needs some on-topicness.
Of course the PS3 controller is the most expensive. It has a 30 hour rechargeable battery, six axis tilt sensing (where do you think Sixaxis comes from), vibration in the DS3, and the sixaxis is extremely light. It uses Bluetooth instead of Infrared, and seven controllers can be connected at once.
It also happens to own the other two in looks.
