concerning the most powerful daedra, i would like to point out that we don't really see how much power most Daedra really have, as they will only use their power when it coincides with their spheres. for example, Mephala might possibly be stronger than Mehrunes Dagon, but if so, we would never see that as she wouldn't attack Nirn the way Dagon did.

as for the coolest, Sheogorath gets my vote.
