Yeah, I misread the original post. I blame that fresh RASS I was having at the time. I listed two cigars that I use for comparison, i.e., if I smoke a new-to-me expensive cigar, I will compare it to a Boli RC - if I smoke a new under-$6 cigar, I'll compare it to a Padron 4000. (I stopped smoking bundle smokes, but those I used to compare to Flor de Oliva.)
Obviously most folks will choose a Padron anniversary over a Padron x000 :helloooo: (and I'll take a BBF over a Boli RC).
One could get stupid and say a Cohiba Behike is the 'standard,' or the 1492 or some EL or similar silliness ... come to think of it, nobody has listed Cohiba (although there are so many fake Cohiba around).
Anyhow, if I interpret the question another way, I'd have to go with the (Cuban) Montecristo #2. It was around before almost all the cigars mentioned, it was famous before almost all of the cigars mentioned, and has been the definition of a "good cigar" before almost all of the cigars mentioned. It isn't the most consistent smoke, it is made in HUGE quantities over many factories, and it isn't one of my favourites, but when I see the words "industry standard" much like a Merc S-class is an industry standard, I think Monte #2. (Among non-Cubans, I see Padron 1964.)
