Both are absolutely wonderful and unique in their own way. I have to admit, while I find the Lange to be a more pleasing view primarily due to the use of German silver and the hand engraved balance cock, beyond that I'm in the camp that says the two are fairly similarly finished. That is to say I don't think one blows the other out of the water here, both are very well finished. With all that said my personal taste has always favored Lange over PP ever since I got into watches, so there's no doubt in my mind which one I'd enjoy owning more.
