I've always liked Tomas Haake, he just looks so natural in his style when he plays. Probably not as technical like a lot of the drummers already mentioned, but he is probably one of the more gifted drummers in metal
Rather biased towards more contemporary prog but this is a list of my most influential drummers.
Neil Peart, Rush
Mike Portnoy, Dream Theater (formerly)
Gavin Harrison, Porcupine Tree
Danny Carey, Tool
Marco Minnemann, Steven Wilson
