Danzo wins because 10 lives and expert use of Ninjutsu. While Hiruzen is indeed the God of Shinobi Danzo has far more loopholes to exploit as compared to when fighting Sasuke, who had an absolute defense. As seen, Hiruzen got hit a few times in Taijutsu against most of the opponents. Against Danzo that would mean instant death.

However, Enma might play a crucial role in this battle, though I don't think his body can withstand wind-enhanced shuriken or blades.

Also, people have to remember that Danzo's strategy against Sasuke was to conserve chakra. Against Hiruzen he would have no reason to do so, and would probably win with Izanagi or pure skill alone.
