As others have said, if movement decoration is priority, the Lange has an edge but I don't see the PP being very far behind. In terms of case design, comfort, dial visual appeal, resale value etc PP holds the advantage. So the "King designation" for Lange is imho very subjective.
Anyway, the 5170P blows every manual winding chronograph out of the water imo including Lange. But yeah, as an existing owner, I am biased.
Bottom line, get what you like.
