To be fair, the Eight Gates has a time limit like we saw with Guy. I don't think Guy would necessarily have taken out all seven either - he had help against Madara and there were a couple of points where if he was fighting alone he'd have been taken out (like when Lee jumped in to get his body out of the way, or after the very first Evening Elephant strike). The ones that survived might simply have outlasted Duy's body.
