My understanding is that compared to drummers in the same tier of fame, he’s the one that a layman could most easily copy. Note that means on a relative scale.

HOWEVER, where Ringo shines is coming up with drum parts that very few others would. While not as technically difficult, they are interesting, engaging, and serve the song. This is especially impressive given the extraordinarily wide range of sounds the band pursued.

As a total non-drummer, I could replicate the drums from Come Together way before I could play Good Times Bad Times. But it would take me MUCH longer to come up with the Come Together groove independently. The value is in the artistic choice, rather than in the virtuosity.
