I really like the yellow - eyed demon because he always had so much control over Sam and Dean, they were his pawns, especially Sam.

he's been the main baddy for like 2 full seasons and with out him there would b no supernatural

I think it's kind of unfair to compare them right now. I mean we've only seen one scene with Lillith. I think this question should be asked after we get to see a little more of what Lillith can do.

He rocks i tink he is toatly awsome

YED was great. He was like the perfect villain. Lilith looks really creepy though... I also think we should wait until we see Lilith in other episodes

She's evil!

Lilith freaks me out, but YED was interesting.

it's scary seeing a littel girl de.

They were both good - but little kids are always creepier.

Lilith is pretty kickass, but YED has some kind of mast plan up his sleeve and I really want to know what it is...

lilith is a little girl which makes it scarier

OMG! i haate! yellow-eyed demoon because he killed the mother of the winchester´s boys and killed jessica too!

I love lilith, truth be told, but Azazel was crazy. Sneaky scheming and Azazel is just plain mean.

Lilith was pretty creepy, but Azazel was a SCHEMER man, to the extreme. 30-year scheme just to get Sam to use the hand of ipecac on Lilith. SCHEMIN!

what for?

I hated Lilith. What a bitch.

she's smarter

I think she's more powerful and higher ranking as a demon

Her preference of possessing little girls was ultra creepy.
