The hardest Balls. From shoulder height, drop onto concrete a medium compression Ball -- so-called 'right' for the average player -- and a high compression Ball -- right for the good player. Which bounced highest?

Now, ask yourself:

Why would I ever want to play the Ball that bounced lowest?

For more control around the greens! Dropping a ball from my shoulder might approximate how hard I hit a chip ... Why would I want a ball that chips "hot"?
I don't believe compression matters like it used to. A ProV1 isn't going to bounce as high as an old Top Flite XL, but I'll bet it goes further off of my driver.
