OMG, thats undecideable to me. Sorry, this is too hard!
First, Kelly's voice is more "commercial" if you ask me... which suits where she is in now, pop/rock stuff. But she's unconsistent, i love her voice during AI and first album which she's doin better in performance too.
In Carrie case, well, she has different "type" of voice. Kinda strong and something "big". Something in her voice made me comfortable in any way, and I can related alot to her songs.
So I cant dfecide it easily.
