Actually, it'd likely be Qusay. He was gathering power behind the scenes, and ran not only the Special Security Organization (SSO) but also the Special Republican Guard. More importantly, he was being groomed by his father to be the successor. Uday was more of a playboy and a public danger (his psychopathic tendencies being well known in Baghdad), to the point of having made numerous non-Baathist enemies, who tried numerous times to kill him. I remember a news story on the two before the invasion, and one source remarked this way: "How do you differentate between the brothers? Simple: Uday kills for jollies. But when Qusay kills, it's business." And it's no secret that before the invasion, both wanted the other dead. Lots of folks were surprised that the two brothers were found together-and died together.
