IMO, the cyborg pearl is longer and stronger
The Kinetic is weaker, but corners very hard, it's a unique motion
I don't swing the Kinetic as much, if I can stay out with it, then it's money.
If I have to go away from the pocket, then it runs out of energy and I can use the Cyborg
You could easily have both, as long as different layouts and surfaces(mentioned already)
It all depends on what holes you may have in your arsenal
