It's the difference between a simple set-up like Ringo's, or an elaborate set-up like Peart's. If I were a drummer, I'd be like Peart. I'd have to have all sorts of different cymbals, toms, bongos, shakers, scrapers, gongs, bells, congas, whistles, miscellaneous percussion gizmos, etc.

And then there are all sorts of sticks, mallets, and beaters to clobber them with.
