Good question
Pert was the best, I had a chance to see him on Rush's last tour. Absolutely stellar.
Growing up in the 80s, prior to all his pop stuff, I never knew what a great drummer Phil Collins was until later in life. I don't known if he would be considered more Fusion or Progressive (somewhere in between) from his work in the 70s and early 80s, i would add him to the list as well. The rest that come to mind are probably more considered Jazz Fusion like Lenny White, Cobham, Gadd etc etc.
