No, I do not think so, and since Brunswick released a lot of balls and coverstock tweaks (even Activator particles themselves!), one cannot generalize.
I can tell that the "normal" Activator on the Inferno was a slight but remarkable step up from the former Aggressive Reactive pearl: more length and more back end, but not an overly strong improvement (there is also core influence).
I think the best bet to have a particle peral reaction from Brunswick is the (discontinued) aging Inferno and maybe the Ambush, which is rumored to have an Activator pearl light load particle coverstock -although I cannot proove it, just rumors from knowledgeable side here in Germany. The Goliath, with an ultra high particle load, is rumored to be based on Activator, too.
The Impulze Zone is Activator solid LLP, best desrcibed as "smooth and strong" on medium to medium oily conditions - a typical particle reaction ball.
IMHO, the IZ and/or the Ambush will probably offer what you might be looking for, even though it is not a pearl ball.
