I have had a PP5396R and I personally prefer its dial to both PP5205 and PP5146, why? Well in my opinion the dial of the 5146 is not well balanced, the subdials at 9 something and 2 something are too close to the centre and the little date at 6 is odd....that is my own opinion, I like the hands and case though. On the 5205 I find the dauphine hands (which I generally don't care much for anyway) are not in proportion with the rest of the dial, too big or fat or something, also I don't like the position of the moon/24h dial. Ok, now, as said I HAD a PP5396 which I traded for a Lange & Sohne Datograph, so now I am biased
but to me as an AC the Lange is far nicer, the dial is so clean, easy to read, well proportioned, open, the shape of the blued hand, the big date etc. So, for me there wouldn't be a second of hesitation if I were to go for an AC between these 3, as one says, y a pas photo! I'll go for Lange!!
