I have found very little difference in taste based on length but a significant change based on RG. I've smoked every vitola of MOW Ruination from Corona (43 RG) to War Horse (64 RG) and there is a very discernible change in the body & intensity of the flavors. There's no doubt they're all related in that the foundational flavors are very much present but it's kind of like the difference between drip coffee and espresso made from the same beans.
