At the risk of pissing off more afficionados than I already have in the last 24 hours, Tony Williams was a vastly better drummer than Buddy Rich.
Rich was an amazing speed merchant and put together some impressive big band music (I still enjoy "Bouncing with Bud" on my 40+ year-old "direct-to-disk" vinyl).
But Williams was the consummate musician. That's admittedly a hard sell, but, when I listen to Tony, I'm always spellbound with his comprehension of the compositions and the way he wove his playing into the other musicians' grooves. He complemented them, and they dug it. His playing was spatial, thoughtful, playful, musical - almost as if he was singing through his gear.
It always comes back to what we individually view as "the best," I guess. Enjoy the music you love!
