ISOMs are in a different class, not that it's a better class (to each their own) just a different class. I think the same is true for PAMs and Opus and I believe, IMHO of course, the Camacho Diploma-11/18. And as such they are tops in those respective classes. I also agree that ISOMs require a lot more humi time (at least a year going by box codes) to really come around. I'm sitting on some nice ISOMs right now, and it's killing me, because I wasn't observant in the box codes and they are simply too young. In a year or so, we'll see. VSGs and PAMs really develop after about 8 months to a year as does Opus and Camacho. All the remaining smokes that I prefer fall just under the above, some closer than others, but given enough time, you can just close your eyes and pick one--you won't be disappointed.
