Mariah Carey & Christina Aguilera....?

i love christina. i love the old mariah.. not this mariah now. shes thinks the world of herself and got a big head compared to the 90s mariah. they both are good singers but christina does good high notes that dont make me want to rip my ears off my head, with mariah just because she can go high and do that ear splitting note doesnt means she should. christinas my pick...

i think of Christina. Mariah is an outstanding singer, yet whilst she performs, its no longer constantly so super. Christina on the different hand is an astonishing performer. and that i choose her voice than Mariah's, in spite of the fact that Mariah has a extra physically powerful variety. Christina's voice is extremely solid.

Mariah Carey ( The Voice ) Obviously had the Greatest Performance!

Christina has good vocals, but her performance didn't really make any sense..

BTW, Mariah 'did' sing the most beautiful song of all time!

I think I am am going to have to go with Mariah, she is the best song writer out there. I love Christina and don't get me wrong. But Mariah has a 7 octave range in her voice and she will always concur over, all her songs have been number one hits, and not only song on all of her CDs are boring. Go Mariah!!!

Should of put Mariah's 'If it's over' , that's unstoppable,

Seriously, Christina isn't even close to Mariah, Or Whitney, She has a horrible jaw dropping technique, She screams it out, So much stars today are better then her, infact probbaly even people on this site

Mariah Carey. She's performing her own song along with other. Her voice and range are also far superior to Christina's. And, in my opinion, Mariah Carey looked hotter in her performance. :)

I prefer Mariah's performance. I think no female singer can hit the notes mariah has through the years with such voice control..she is a freak of natue.. no female can touch her now, or ever.. diva. But this is just my opinion;)

Mariah Careyy. (: She's amazing. I love Christina too. :P She's incredible, but I just think Mariah is a little bit better.

I love that song by Mariah, but that is one of my favourite performances from Christina Aguilera, so I choose Chrissy.

Hmm, i think Mariah's :) I love them both, but i think Mariah has a better voice and i like her better.
