I love them both but Bonzo would be my first choice if I was auditioning drummers for my band in 1968.
Pat's Delight (Bonzo's drum solo in the early days before it morphed into Moby Dick) and Moby Dick itself are ok but I'd rather listen to his contributions to the fine Zep catalog. Aside from his unique flavors, his solos mainly incorporated a good amount of the standard licks long found in classic jazz drummer solos.
He was a superb timekeeper and can soul and funk it up as good as any of the spot-on Motown or Stax drummers. Even in the later years, Bonzo could deliver the goods. His playing matured well. He was firing on all cylinders during the Knebworth shows in 79 and the subsequent Tour Over Europe in 1980. Before his untimely passing, discussing the next album, Jimmy and Bonzo were going to dish up a more heavy, guitar slamming affair, a bit less keyboard orientated than In Through The Out Door. Alas, it was never to be.
Moonie is awesome. I love seeing the early footage of Moon working his high hats before he pretty much abandoned them in favor of his signature ride cymbal wash/assualt, which is spectacular in and of itself. Nobody could touch him. In contrast to Bonzo though, Moon did deteriorate a bit in his later years although Who Are You contains some brilliant playing. It's one of my favorite Who albums.
