Technical ability wise.
Petrucci = Portnoy > Myung = Rudess >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Labrie.
Labrie just flat out sucks, even most DT fans should know that.
You can name 10 better drummers than MP, big deal, i can name 30 better than Petrucci, 30 better than Myung and at least 20 better than Rudess, all you did was laugh it off without trying to make a valid arguement, which is how you like to argue things, you're just like the KISS guy only you say things like "lollolol" and "rofl" instead of "in your opinion"...Its basicaly your way of saying "i have nothing important to contribute to this forum".
You shouldnt even bother making a reply prog metal boy, im not the worlRAB biggest technical skill expert, but im damn sure i know more about instrumental ability than you do.
I can also name more skilled players than petrucci, from every genre too, except maybe the blues, because the blues simply isnt a very technical chops oriented style of music.
^ By the way folks, this guy actualy included Kurt Cobain and Robert Smith on a poll of the most technically skilled guitarists of all time...Im not joking, though i wish i was.
