I agree with you 100%, Iron Fist. Mikkey is a monster drummer, but Philthy had a totally unique "busy" style that was instrumental in creating the signature sound of the band. His double bass work was great (but maybe not like a clockwork) and he was a wizard with the cymbals. Philthy could also add a few surprises when playing live. Other examples of Philthy's greatness: The Chase Is Better Than The Catch and Bomber. They just don't sound the same without Philthy. His drumming on tracks like Motorhead and Iron Horse is also totally inimitable. Examples of Philthy songs that Mikkey performs really well: The One To Sing The Blues, Ace Of Spades.
