Idina Menzel. Though I love Kristen Bell's voice, nonetheless.

By Far! :)

I love both their voices, but for me Idina's voice will always be the best :)

Both speaking and singing. c:

^Same!

By far

Idina's got a powerful voice.

Powerfull and unique.

By far. Both speaking and singing. I'm surprised to see that more people like Kristen's not so trained voice to Idina's trained voice. A friendly reminder that Kristen is just an actress while Idina is a Broadway actress/ singer. But I guess some people like Anna's vocie because it is bubbly and childlike. It's their opinion by the way.

Anna's is annoying.

I love both but by far

I don't really like Anna's all that much.

This is no contest.

To the user who said that Kristen is not a broadway singer, she's classically trained and has been featured in musicals like Huckleberry Finn

Idina Menzel sounds like she was trying way too hard to sound young.

by far!

@Shiki_Otherside Oh, thanks for telling me. I really didn't know that. Still Idina obviously has more experience. Kristen herself told that she was so excited to sing with Idina.

Kristen's voice is not very unique. I love it but i have heard so many voices similar to that. Idina on the other hand has a wide range, a unique voice, power, and an amazing tone. While Kristen does too, Idina has more experience and just overall a nicer voice.

I'm not a fan of either one, Anna is just a poor man's Rapunzel, but at least she HAS a personality
