Since the Venom is the strongest backend ball you mentioned, AND others have told me the CP is stronger than the Venom, I'd have to say it's in the range with the Break Pearl. The Cell Pearl, as far as I have seen, is one the strongest backend balls currently available. The Kinetic is a solid but has a very strong backend. If anything, it would be in that category.
Keep in mind, a lot depends on the bowler's release, ball speed and the usual suspects. I've seen people pipe up the 7/8 board and I've seen people cover all 40 boards with it.
