This is going to sound very "touchy feely" and very "60's" and "greeting card", and that's really unlike me.
Yes he is a great drummer. There are many great drummers including some none of us have heard of yet. Isn't that enough? What is this need we seem to have to name "the best", "the greatest"? Can't you just enjoy a person's skill at doing and participating in the creative act? In you last response you praised Carter (who I think is incredible,and also wasted on the music he's playing with) and in the same sentence, you trashed Mike Portnoy and Neill Peart (who happen to be great drummers although Mike Portnoy's playing is not to my taste.) Dave Weckl is a phenominal drummer, but the type of jazz he plays in not my taste either. I can enjoy all of them as great craftsmen and talented musicians even though I may not want to listen to the type of music that they are playing. How about Steve Gadd as a solid incredible drummer? There are just SO MANY. I enjoy them all, and learn from them all. And yes Carter Beauford is one of my very favorites.
