It would really be hard to quantify "hardest hitting" ball into a single summarially transitive.
There was a study done recently ( within the last year, I believe ) that was published in a bowling magazine. Sorry, I don't know which one because the article that I was shown was no longer in the magazine as it had been clipped out by the person who showed it to me.
What it was, was a study on the effects of total weight and hitting power on a ball. It was shown that the major factor in "hard hitting" wasn't necessarily just brute weight, but also getting the ball into a true, full roll at the pocket.
I can't remember the actual numbers in the equations, but suffice it to say that, through mathematics and physics, it was shown that a true rolling 14lb ball will hit "harder" that a still skidding 16lb ball. That was because, while the ball is still skidding, it cannot efficiently expel its full energy on the pins, thusly reducing the "hitting" power significantly.
Now, if you want to say that we live in a perfect world, and every ball will enter the pocket at the same angle and in a true roll, the ball with the most total weight, best C.O.F. ( co-efficient of friction ), and C.O.R. ( co-efficient of restitution ) would HAVE to hit harder.
