Yeah Darkside is also one of my favs. Lately Luana Dametto from Crypta is also impressing me a lot. She's not the most technical out there, but she uses her skills 100% to serve the music and never to show off. She is very groovy.
For technical proficiency I feel like Mike Portnoy may be the best out there, but Haake is much more innovative in his approach. My personal favorites are Baard Kolstad and the drummer of Birds in Row though, love their styles.
