All subjective.
Example...
Lets compare two cigars to be had. The popular Padron 1926 serie and the elusive Opus X whatever vitola. These two can be called super premiums based on quality of smoke, however one is considerably limited as compared to the other. However, others might consider the Padron 1926 Serie to be a regular premium and the Opus X a super premium when incorporating the rarity and high demand.
Another comparison would be to consider any of the Arturo Fuentes (regular line such as Chateau Fuente) to a Punch Champion. These two cigars can be called premiums based on again the quality of the smoke. Again, being subjective, some might call just the Chateau Fuente line premiums and the easily overlooked Punch Champion a yardgar.
When I purchase sticks from a retailer, either online or at a local B&M, I ignore everything that eludes to the word premium, much to the same effect as if they were to describe a smoke as "Full Bodied". These (imo) are just terms to spice up a cigar to the height of adoration. Once you start actually looking at cigars, you can get a sense of what good tobacco is. How it smells, feels, tastes, and from there you can draw your own conclusions as to what a (super) premium should be.
