Nico, haven't seen any of them in the metal as of now, but I would think - judging from the stock photos and the ones you took - that the rose gold variant would be a better looking watch with a bit more contrast on the rose gold casing and the dark grey carbon fibre dial? I would've liked the SS model as much if there was more contrast between the dial and case...
However I might be totally wrong though. Since you've seen them both in the metal, give me your two liras Italianas!
