I, like so many on this board I assume, have dug deep into the Soundgarden catalog.
Currently listening to 'Live on I-5'.
Matt Cameron is the guy. He's got the power, and the ability to seamlessly shift in odd time sigs.
He's also got one hell of of a pocket. You won't catch this guy rushing through shit, and he would be one of the few I think that could handle the newer Rush material.
He's also got a Geddy record under his belt.
'Cameron, Lee, Lifeson' has a nice ring to it.
