Haha, I found a picture that puts my thoughts on the controllers much more simply.
People saying that the Playstation controller is the unsymmetrical one... You don't put your hands on the face buttons. They don't belong there. Your two thumbs stay on the analog sticks the entire time. If you do end up having to press a face button, you're thumb flies to the face button, clicks it, and flies back faster than should be perceivable by the human eye. Why would you ever leave the thumb on the face buttons?
Also, why would your thumb ever go up? When I let my hands go limp, my thumbs point sideways, not up. You have to constantly be holding your thumb pointing in the wrong direction to use that left stick. It makes the Xbox controller so hard to use! It is so weird for me to think that most people's thumbs don't naturally rest above the dualshock analog sticks.
