So many people like users and developers using them so far and no big reports of its issues have ever come. Your issue could be on the controller which is faulty or not final retail one. I'm sure that sony have tested the controller for roughness in their lab and been used serveral times by many different hands, and the problem ones we find could be because of the manufacturing defect.
GAMING is not about spending hours to pass/waste our time just for fun,
its a Feeling/Experience about a VIRTUAL WORLD we can never be in real, and realizing some of our dreams (also creating new ones).
So, Feel Emotions, Experience Adventure/Action, Challenge Game, Solve puzzles and Have fun.
PlayStation is about all-round "New experiences" using new IP's to provide great diversity for everyone.
Xbox is always about Online and Shooting.
Nintendo is always about Fun games and milking IP's.
