Obviously, you've never listened to anything remotely close to the entire catalog. Peart is by far better not only technically (what else is there, really), but also plays a "loose" style as well.
I've often considered Peart to be a highly skilled and disciplined version of Keith Moon . . .

Sorry, but I've been around drums for almost 30 years, and there just aren't a lot rock drummers who should be mentioned in the same breath as Peart. Jazz on the other hand . . . .
