I asked my boss who runs PZ4 on his McLaren and Porsche, and PS4s on his Aston, and he reckons for everything he does (fast German roads, camping, super market trips, length of the UK drives) both are fine and you can't go wrong with either. He's strongly opinionated if he believes real differences exist, and in this case he doesn't. A personal opinion from someone having both and running both counts more than things online.

Reviews differ from anecdotal evidence from owners I find- hard to give Pirelli’s away on performance car forums.
