@Nemra exactly. Most people in the industry know what great voices and, and they have made it known that Christina fits the billing. Beyonce isn't known for her vocals sorry. Resentment to me was one of Beyonce's best vocals, but she almost had to turn herself into someone else to accomplish that, but guess what that song still does'nt stand a chance against Christina's ballads and yes from a technical standpoint. So i'm staying put Christina is by far the greater vocalist. She has it all. I hear lots of variation in her singing, something Mrs.Knowles lacks. All of her vocals same the exact same.

Beyonce's head voice is average. I just don't hear much sould in her voice may'be sometimes but not overall. Christina's vocals have so much more passion,power,emotion and depth. She's the epitome of a vocalist. She's doing something right because she has become a staple for her Vocals. So YEAH !!!
