User blog comment:Bharatram1/Who is stronger ? Lilith or Azazel ?/@comment-3481504-20120428233313

Up above, in the voting box, I voted Azazel. In spite of the fact that it may seen opinionated and/or speculative, it isn't, really.

See, while the writers haven't revealed in Salutes, magazines, or ComicCons, the episodes in which these demons appear says it all.

In the field of possession, Azazel can possess a Reaper, which, by the way, no other demon has done, including Lilith. In one instance, he he was vesselless, in "All Hell Breaks Loose - Part 2", he was in the form was for a moment, a humanoid shadow.

He possessed astounding strength in and out vessels, even his smoke form was powerful, enough to break things.

Also, he was the only demon to have manipulated the weather, a power which is know to extremely powerful forces.
