As a classic pitching/directional hitting 'clean screen, no vibration' guy, I look for a difficulty setting that maximizes player ratings vs user input. In my opinion, the difficulties above All Star begin to dilute that a bit as the CPU begins playing more and more above their ratings. That said, I have found that very modest one-click slider changes can amplify the mental challenge of the level a bit more. But, that's me...and for me it is perfect.

What is "perfect" for you may be quite different based on what is most important to you.
