It's been mentioned and seems to be generally accepted that NC's are not suited for long term aging. I have a hard time believing this. I've smoked some 30 year old Dominicans that, to my taste, are significantly better than anything being produced currently with Dominican tobacco. Maybe the crop is different now, or the blending styles have changed over the years, but I would be leary of counting out all NC's for aging potential. I am especially interested to see what becomes of some of the fuller flavored spicy/sweet Nicaraguan puros.
As for the debate at hand, I would have to put myself in the both category. I enjoy the flavors produced by all the various tobacco growing countries including but not limited to: Cuba, Nicaragua, Honduras, Brazil, Costa Rica, Ecuador, USA, and maybe least of all, the aforementioned Dominican Republic. Quality control is deffinitely a benefit of NC's. An educated smoker can rely on any number of bargain, mid priced, and premium NC's for uniformity, draw, burn performance, and appearance. On the other hand, there is no doubt in my mind that the best cigars ever made were made in Cuba. I think most "real cigar smokers" would prefer to be smoking 20 year old Cubans on the daily.
