Danzo, high diff. Izanagi rewrites Danzo's personal Fate, if too many of his chakra points are blown he can simply activate the jutsu. And his sealing technique would be murder for either shinobi here.
Base Lee has no moves to kill danzo with while danzo has plenty of distance moves with his futon and Baku plus wood element if he really needs to and as long as he keeps his distance from neji, he won't need izanagi until lee goes gates
