Well... In France, we are lucky to have the "official cuban cigars". During last years, I smoked a few different cuban cigars, some were mild, some were strong, some were sweet, some smelled barnyard-ish, some horse barne-ish (good), some earthy, some woody, some cedarish, some coffeeish, some caramel-ish, some were complex, some were simple, some were "Special Edition" or "Regional Edition", some were classic, some were too "green" (young), some were old, some were cheap, some were not cheap... and (of course) some of them were impossible to burn because of a bad contruction (too tight, no air flow).
Some of them were amoung the very best cigars I have ever had (rare), a lot of them were just "ok".
I did not smoke every available cuban cigar, but I smoked a few different one (when I was still buying commercial cigars)
Something I can say is that most of them had a little something that was distinctly "cuban" (a similitude in the taste, hard to describe, I would say "creamyness") that I hardly find in other countries. It could have something to do with the cuban "terroir".
I have smoked more cuban cigars than any other county, the first reason for this is that they are/were easier to find (in France) compared to cigars from Nicaragua/Dominican Republic/Honduras...
