No, I make this assumption based on the fact that Porsche is a much larger volume car dealer and therefore has manufactured and developed these brakes for a variety of cars in much greater numbers than ferrari. Coupled with this extensive developement is the fact that Porsche must have a higher reasearch and developement budget due to the fact that they sell so many cars and are the most profitable carmaker in the business. After producing or purchasing and testing so many pccbs for a wide range of cars, Porsche has had more time/experience to iron out the bugs and improve the system. These may be assumptions, but they are logical ones and until a comparison test is done, I don't know how we'll prove it one way or the other.
