I'm going to say 1a.)More or less, so to speak. 1b.) To some extent, yes. At least I can't think of a cc that lacks it, except maybe RS12's. 1c.) I don't consider it a "smoothness at all. Just a weak "rosey sweeteness" that gets overpowering in some cigars, is very faint in others.
For part 2, I have to go with your ribeye hypothesis. Sometimes I love a Los Statos or La Corona. Sometimes a Cohiba cigarette (which very much brings that hay sweetness to the forefront). It all depends what I'm in the mood for, and how I want it delivered, and at what "speed".
I seldom have a desire for that distincy cc flavor, as I enjoy more body, fullness and in the faceness that different nc's impart.
"Good" or "better" is wholly subjective. That's why it's an argument that goes on forever and can never be won. It makes for interesting conversation, or downright disdain, depending on the parties involved.
Sometimes I really get a hankering for a crappy cc, sometimes I get a hankering for a "good" one, but mostly I enjoy the package a Nic puro brings along, or a Dominican puro. I don't feel any are necessarily "better" than the others, but more that different profiles fill different temporary desires.
Kinda like women.
