I would say the Paranoia is just a stronger Octane. Since you already have the Primal Rage and the Octane, I would go with the Octane Burn. Great ball without all the unpredictability of the Paranoia.
Unless you need a ball to move WAY left and have it still turn the corner hard and kick out the corners, then I don't see much use for the Paranoia.
If you can repeat shots almost exactly, the Paranoia has the biggest back end move I have seen in a Motiv ball. Miss slightly and you will pay a big price. And once there is carry down, it just squirts past the break point. This thing is more unforgiving than the Octane.
The Burn on the other hand, gives a nice arching motion and still moves nicely off the friction at the end of the pattern. It's between the Tags and Revolts both in strength and shot shape.
