How long is a piece of string
For sheer heavy rock power I would say John Bonham from zep or bill ward from Sabbath
Ginger baker of cream was brilliant
Keith moon was a heavy drummer and Ringo Starr was very much underrated
But for sheer all round skill I would say Neil Peart from Rush
Mind you a lot of the new crowd know their way round the tubs , helmet , queen's of the stone age , every time I die and Mastodon all have great stickmen
