I worked in Havana temporariy in the late '80s and early '90s, before there were many good cigars anywhere. Today, there are many that match the Cubans for "goodness", but a good Cuban still has a certain flavor... The best rolled, then, came from the Jose Marti factory and most brands (nearly all made in the same place) had "JM" in blue ink stamped on the bottom of the box. The fakes then, as now, were indiscernible from the genuine until you smoked them. (The fakes weren't that bad, either...)
I'd get some fine, current brands going so you can tell the difference. I'm not current with the myriad of new brands -- so many are good -- but, I do seem to prefer Nicaragua wrappers. Once you know those flavor, you'll catch the difference. (They were $25 a box for all but Cohiba, which were $40 - $50 a box.) I'd smoke a couple now, too.
In the lower level of the Nacional hotel they had a lonely old "roller emeritus" sitting all day, with few people walking by. He'd roll whatever you wanted and I could not resist smoking it immediately on a walk. Wet, green, whatever, they were wonderful.
