I am currently agonising between these two heavyweights, except I prefer the 5204 with the white dial. Simply put, my heart tells me Lange, my head tells me Patek. Aesthetically, I find the Patek falls short. I dislike the superluminova markers and off centre subdials. I have to admit though, I am impressed that PP managed to fit such a complication in a 40mm case, although it doesn't feel as proportional as the Lange.
