The obvious answer would be Hermaus Mora, Malacath, and Azura. Because they are worshiped as gods in multiple cultures, which would require a lot of power to have such an active role in everyday life.

If the Daedra gain power from how many people worship them and how fanatically the worship is done, and how active their sphere is in the world, along with some natural power. Which would explain Mehrunes Dagon's power difference in Oblivion and in Skyrim. If that was the case then Azura, and Malacath are the most powerful and Sanguine is the weakest, because merry-making and debauchery are very scarce now, at least in Skyrim.
