I feel like they both have nice, soft voices but I think Selena has a clearer, more powerful voice than Miranda :)

I like Selena and Miranda but both have not special voices to me
I don't get impressed easily by singers of this decade :P
Well,it makes sense of course

I think Selena has a better voice because it's more powerful and has a larger range, whereas Miranda's is a little flat and sort of emotionless in my opinion.

They're both very similar in my opinion. I think they both have decent voices, although I don't find either of them to be anything special either. I think I prefer Selena's voice just a little because she seems to be a bit more expressive.

Both have good voices but I think Selena's voice better.

I don't really like any of their music, but I think Selena's much better than Miranda.

Selena isn't great, and Miranda's voice, to me, is like nails on a chalkboard.

No doubt.
