christina aguilera is the best!!!!!!!!

No competition at all.

agreed!

Loved Amy Lee since I was 8, so it's an automatic win for me. =)

btw you realize that this is STRONGEST VOICE not FAVOURITE?

I cant stand Christina Aguilera, I much prefer Amy Lee! But Christina has a stronger voice in my opinion.

This was an incredibly hard choice o.o

I picked Amy Lee b/c her voice has more of an 'impact' for me. Christina Aguilera is incredible, but just doesn't have that impact for me.

But only because it's rock.

Amy has one of most powerful voices I have ever heard. She is my favorite female vocalist.

i agree with gothgrl3249 :)

I looovve rock and i looovveeee Amy!!! <3 but at live performance is Christina's voice stronger... i think Amy's voice is more beautiful than Christina's cause NO ONE can sing like Amy! <3

Ugh, this pick is too hard!

I loveee Amy too much not to pick her!! She has an incredible voice...she's one of a kind..and she can pitch notes that i never new existed:) One of my favourite singers<3

I just love her voice!!!
I love evanescence!!!

I love them both! If we would talk about beauty of the voice, I would pick Amy, but Christinas voice is stronger and live performance better.

amy lee has an amazing voice better than christina
