Drummer. What the hell. I actually think that this is one of the few polls that makes sense. Both are fairly similar neo-classical prog metal guitarists, and share a lot of influences. Their music is fairly similar, and they are fairly similarly skilled. That's the point of a poll. This isn't apples to oranges here, it's more "red delicious" to "granny smith".
Let's think before hopping on the "no more music polls ffs" bandwagon

I respect Steve Vai more. He seems to be less egotistical, which means a lot in my books.
