I've heard that most CC's can't hold a candle to a certain vendor's sun growns in blind taste tests and that Cuba is actually net importer of tobacco so they're mostly NC anyways,
Personally I smoke Cuban's almost exclusively, the only NC's I've found worth a second try are Padron's, Alec Bradley's and the Oliva V and O series. All the rest I've tried just don't appeal to my palate.
