I'd be the last one to bash Portnoy, as I love all of his drumming, and I've watched Liquid Drum Theater more times than I'd care to admit. But it's still important to put his abilities in perspective: what he's absolutely brilliant at is contructing parts that mate perfectly odd time signatures and quirky ideas of the groups he plays in. He isn't, however, a drummer that shuts down every drummer in every way (and no drummer ever could be). In terms of seamlessly integrating odd time signatures, I'd pick Danney Carey (Tool). In terms of raw speed, there's a whole list of death metal drummers that are going to be faster. In terms of tasteful speed, think of drummers like Buddy Rich. So a comparison between Portnoy and Morgan Rose just doesn't make much sense. Rose is mostly smashing out power grooves that drive the music, while Portnoy is mostly playing tricky hi-hat/splash accents in odd time signatures. It's like talking about a hip-hop group that you like and someone says "yea, but what about The Beatles?"
