Cannot comment on the Vinceza leather but I have a BK Liberty (veg tanned hide also from Italy) that is markedly different from my Aero FQHH. Neither one is "better" than the other but as has already been said just different. The BK hide is much lighter, more grainy and has what I would describe as a more natural, organic look and feel about it. It is very beautiful indeed. My Aero FQHH on the other hand has a wonderful depth of colour that seems to change the more wear it gets. I love both!
