5004P...
I would definitely take the 5004P not only because it stands as one of the true icons of Patek's numerous horological wonders but it is also pure, classic and unswayed by trends thus showing vividly the traits which endear Patek to its fans. Having said that, I too wonder if fans of high end technological watches really want diamonds on their wrists.
As for the 5970, with its nod to current trends of slightly oversized case diameters, I prefer it to be in its purer form, either in WG or RG, sans diamonds
