I agree with
@Glassman here in the reaction of Jfire's Rh comment. From the original question, my reaction is to comment on how cigars taste and perform, from box to box, over the years. A certain cigar can taste very different over the years and Rh will have nothing to do with that when it comes to that years harvest, tobacco quality etc from year to year, box to box, factory to factory. The factory where it's made can make a difference too even in the same month of factory code...
I've learned over the years there is no real consistency for the most part... you can find some dud boxes for most everything. I've been chasing the memory of a great box of BBFs where others haven't even come close. I can have an outstanding box of ERDM Choix, and others not even close. I've had some great Upmann 2's whereas I've had some dark wrappered ones that were trash to me.
In my experience, the one cigar that sticks out for being consistent is the Party Short... it's been hard to find one that isn't really good.
