Fuente's Opus and Añejo's are strong, yes; but there's also a depth of flavor, a complexity that you...well, that I don't get from a Pepin or a Tatuaje.
Plus, there is no baseline for comparison of the real, true test of a cigar's quality - age.
Pepin hasn't been around long enough (in this present incarnation; El Rey de Los Habanos has been at the same spot since I can remember) to have had any of his cigars stand the teat of time, which only a cigar with genuinely fine tobaccos and impeccable construction can.
Don't get me wrong; I'm not down on Pepin at all; but the facts are irrefutable - they just haven't earned the chops that Fuente has.
An interesting exercise would be to find some Pepin's from their inception; then find some Opus and Añejos from the same year. Put them away for aging, and taste a sampling in 5 years...another in 10.
