Exclusivity, Perceived Status and Card Durability all seem like great reasons why you should upgrade from plastic. Don’t you think? We do.
"Perceived" status. At least they're honest.
I think metal cards are cool, too...but I don't think I've ever even held one and I doubt they really impress that many people. You'd have to hit the perfect intersection of people that pay enough attention to credit cards to know metal cards exist and are supposed to be an elite product BUT don't pay enough attention to know what's out there and how (non)exclusive they really are.
