I would say that Bonham is in my "top 3" of favorite drummers, along with Keith Moon and Ginger Baker. I suppose that Bonham is most noted for the sheer power of his drumming, but he also swings pretty well on the bluesy songs.
I think it is interesting that Ludwig sells a replica of Bonham's kit from the The Song Remains the Same movie. See this link:

I don't recall the movie enough to know if it is exactly the same, but what's interesting about it is that instead of having two drum-mounted toms and one floorstander, it has one drum-mounted tom and two floorstanders, for a deeper, fuller sound. In any case, its popularity is a tribute to Bonham's reputation.
