he's only known as a drummer for 2 bands (does he still play drums for QOTSA?), and even then barely anyone knows him for crooked vultures.
Nirvana
Foo Fighters
QOTSA
Them Crooked Vultures

It's not even close
He doesn't drum for the Foo Fighters though
He played every instrument on their first CD so I'm counting it.
Plus, starting one of the most successful current bands by himself is still a pretty good accomplishment for just a drummer.

This is the discography of American session drummer and songwriter, Josh Freese. Freese has appeared on close to 300 records. Freese is an original member of A Perfect Circle and a member of The Vandals as well as DEVO. He was the drummer for Nine Inch Nails from late 2005 until late 2008, and for Guns N' Roses from mid-1998 to 2001. He is currently performing live with both DEVO and Weezer.
George Kollias
Kollias wins the best technical skills award, but he's only been in Nile for 3 albums and not much else.

Video of Travis Barker in a drum off with The Roots drummer ?uestlove. Travis is damn good, but ?uestlove is fucking incredible.
Grohl, to me, is more an all around musician than drummer. If you've ever seen Foo Fighters live, he kills it on guitar and vocals (even screaming in some songs that actually sounds great).
Drumming, I wouldn't say he's the most accomplished and while he's a good drummer I don't think he matches Portnoy's technical depth/ability/speed on the drums nor Peart's creativity with sound sampling + genre hopping nor time signature ability of both.
Grohl is all around a better musician than both, however. Hell, he not only wrote the lyrics for all FF songs but the melodies with guitar and a huge portion of drums which, while not complicated, is still very impressive to think that he did all of that himself. Then he sang the songs for Foo Fighters and went platinum on six albums and won 3 grammys. Probably the only musician that can come close to Grohl is Jack White.
So yeah, Grohl is the probably the most accomplished musician just off Foo Fighters alone but not as accomplished on drums as say, Portnoy and Peart.
Well then fuck, I'd say Josh Freese pwns Dave Grohl

Everybody and their mom wants Josh to play with them.
