I will state objectively that although John Bonham is a very good drummer, but Neil is better. Bonham has a lot of rhythm, or as others described as "feel." But, like many drummers does not inspire. In this case, drumming sounds like a great deal of rhythmic noise with no detail and eccentricity.
Besides, Neil has all those attributes of "feel" as well as being very technical, combining many disciplines of drumming. Perhaps, at some point (60's?) there was a shift in rock music, concentrating more on "feel" then on the "technical." Thus, Neil does not get noticed by the normal mainstream. Sure, he is consistently recognized as on top by other rock drummers or aficionados. But, if you ask any average rock music listener they will say: "Neil who?" I know this because the situation has risen many times in music conversations with me winding up saying "never mind."
