I have always found a lot more depth, flavor and complexity out of nc's, as a whole. By a longshot.
I'd be willing to concede that cc's deliver more "complex subtleties" than nc's, as a generalization.
Mind ya, this is just how I feel, but I find cc's as a mild alternative to a good cigar. I don't mean this disparagingly at all. I enjoy a number of cc's now. I smoke them when I'm not in the mood for a cigar.
I smoke strong, sweet, spicy maduro nc's mainly.
To put it in perspective, I feel like those nc's are a big steak dinner and cc's are a salad. Sometimes I'm in the mood for a salad, ya know?
I find all my cc's so similar that if I was forced to only smoke them, I'd probably quit smoking from boredom. There's not the vast difference between a nic puro and dominican puro. I enjoy that big difference, the big range.
Ultimately I think it's awesome that there's so many different origins, and so many different blends. It's what gives the whole hobby spice.
One last thing and I'll shut up...
Nose a two year old JJ Maduro and there's an absolute mind-blowing richness, huge range and complexity at a 10 on the Richter scale.
Nose a 10 year old ERDM Lunch Club and it's like going to the ballet. With a dress on.
It's whatever you're in the mood for, baby.
