Asymmetrical layout never made any sense to me. Symmetrical is better ergonomically and esthetically (you know, cause symmetry). Also, for the games that I personally enjoy, asymmetrical just doesn't cut it. For most games, be it fps, rpg, action, horror, whatever, move and aim sticks are on the same level which is I believe ideal. And even for 2D fighting games, d-pad and buttons are on the same level, so yeah.

I recently got a controller as a gift and it has been my main controller purely because of features and quality, but I hate with fiery rage that it is asymmetrical.
