All joking aside, to me a great cigar is defined by more than just the cigar itself. An okay cigar can be a great cigar if I'm around the right company while smoking it. Or if I'm eating something before and/or during that pairs perfectly with it. Or if I'm drinking something that makes it more impactful. Or where I am when smoking it and what brought me there (i.e., vacation, work, new place, familiar place, camping/hiking, tailgating, vHerfing, etc.).
On the other hand, a unicorn cigar can be ruined based off of what ambiance is around me.
