User blog comment:Bharatram1/Who is stronger ? Lilith or Azazel ?/@comment-4011543-20120504135517

Azazel, definitely. Lilith had to die for her creator to walk the Earth - Azazel didn't even have to sacrifice himself or anything. Azazel also created his own human army by giving children his blood. Azazel wandered the Earth for years seeking the door to Lucifer's cell. Lilith was trapped in Hell until AZAZEL released her. Lilith walked into the police station; Azazel would've teleported in and snuck in behind an officer like he did in Sam's nightmare. Azazel is by far the strongest, as he is strong enough to persist as a nightmare in Dean's Djinn hallucinations in Season 6. I somehow doubt Sam could kill Azazel with demon powers. I think the demon categories go like this:

Yellow-Eyed Demons (Highest)

Monocoloured-Eyed Demons (Second highest)

Red-Eyed Demons (Third highest)

White-Eyed Demons (Fourth highest)

The demons like the one who possessed Meg (Average)

Black-Eyed Demons (Lowest)
