I have 2 paddel Scuf on PS4, Elite on XB1.
The Scuf is just a missed standard controller, the build quality goes down a bit because there's a split between the back and front parts of the controller.
The softer rubber on the rear plate does feel a bit nicer on the hands tho.
The Elite controller is by far better quality. Such a nice product (apart from the battery situation).
...but I don't like the size/layout of Xbox pads and really like PS controller size/layout.
Found it hard to play Destiny without the paddles now (I use jump/crouch). It's the map transversal that makes a difference, I'm not getting more kills, just feels more natural and map transversal is better.
