There is a pretty big difference outside migrating factors: Madara as much as I hate is not only tricked planned to keep most in what he thought was a dream they'd like while he would then remake the world boiling down to world conquest, Obito was a bit less selfish as well as tragic with the goal of basically putting everyone in their ideal world via dream and remake the world in s utopia and/or join them in that dream world so everyone could live forever in their own utopia and Kaguya just planned to turn everyone into mindless immortal entities devoid of chakra but they'd not be suffering boiling down to world conquest grand scheme.

This guy on the other hand wanted to kill everyone solely to gain enough chakra to make a magical fruit to gain godlike powe and immortality because he felt entitled to it. Even the others wanted people to live be it as servants (Madara), as twisted version of peace as mindless followers (Kaguya does mention it looks like humanity has been hurting her "nursery" is the world or to bring an end to suffering forever (Obito). For this reason I believe he stands out albeit barely based off what I've read on the sites.
