I'm just gonna give a brief defense of asymmetrical sticks: If you consider the upper spot on a dual analog controller to be "default," "primary," and more comfortable than the lower one, then putting an analog stick there on the left side of the controller makes sense for the majority of modern, 3D games, since that's what you'll be using most of the time. Whether you put buttons or another stick on right right side is a tossup, since there are still a decent number of games that have you using the face buttons more often than the right stick. One could argue that the Wii U Pro Controller is a very good design because it puts the more commonly used input in the default position.
People who say they don't understand asymmetrical analogs are probably people who disagree with the bolded statement. Keep in mind that this also ties into the way the controllers' handles are designed - You grip an Xbox 360 controller and your thumbs naturally rest in the upper positions because you're tightening up your entire hand. DualShocks, which are supposedly lightly supported rather than gripped, don't have "default" positions in quite the same way.
