I voted for the black MC.
I once bought the Sarah wallet in Pomme Vernis and I returned it for the Zippy. I had read a few things about the Vernis material not holding up well to the wallet being opened and closed constantly, causing wrinkles or cracks.
If you're going to get a Vernis SLG I would recommend getting the Zippy as the "bend" doesn't go through the same large range of motion. Sarah looks better in Canvas in my opinion!
As for the fingerprints, I barely notice them on Pomme! Maybe get a lighter colour Vernis if you're worried it will bother you?
