It seems everyone and their mother has some iteration of the Cartier love pieces whereas the Bvulgari pieces are more under the radar and unique. Just my 2 cents--enjoy whichever you choose!
I would choose the love over the bzero. I love bulgari but this particular piece just doesnt wow me. If you really like the cylindrical style, I would recommend looking into chaumet's bee my love necklace.
I’m not really a fan of love or bzero. But in this case, I would pick Bulgari, because the design is more unique. Two interlocking circles is a very overdone design, and there’s nothing about this love iteration that looks distinctive
