Anyone who imitates Dylan doesn't have my attention for long.

One of the best compliments I have ever gotten was this: "I have the feeling that when you sing you could be singing in Greek and I would understand every word."

I have always put diction above all else in the delivery. Now, you can go too far in that direction, Hank Snow did that. His affectations were a bit irritating, but you never had to wonder what he was saying.
