For me, the 5970P is the nicest of the regular productions. The black dial is different to that on the gold versions as Patek slightly increased the size of certain numbers on the dial and completed the chapter ring. Platinum case is also just a pleasure.
If one could pick though, id most certainly want to own the 5970g salmon dial from the London exhibitions. To me the coolest perpetual calendar chronograph from patek. Picture from the www
