You must be a very special customer of Patek. Well done on securing all three! Like many others, I am waiting for the rose gold version and I pray it will not be discontinued until we all get ours!
I live in Europe and originate from Malaysia so the white gold version is a bit special for me. More objectively however, I too agree that the rose would be ranked first for the warmth of the metal and the perfect strap combination, followed by the white and then the yellow.
I will congratulate you in advance for securing the platinum version which I have little doubt will be in your collection when it is released.
Thank you for sharing the lovely photos with us.
Best wishes,
