Frankly, I'm not willing to invest the time to check velocities or other differences. If the projectile is the same, other than speed, (and cost) , there is no difference, given similar accuracy.
I'm happy with the KO's. The Brenneke brand was the leader until Kent figured out how to put them on the shelves cheaper.
As Dave says, no slug lacks slap down performance. I like the inexpensive price and the accuracy.
