Apples and oranges. They're both great though; I'd say the current formulation of Cuir de Russie is better than the current formulation of Bel Ami, but I am super partial to CdR. I'd say it really comes down to what you are looking for style-wise. Bel Ami is a more traditional men's scent and Cuir de Russie is plush and luxurious. Both do have strong animalic (read: barnyard) aspects to them, so there's that. I dunno, I just never really picture them as neighbors.
