Leona Lewis
Christina has an amazing instrument, but I view Leona as a more skilled vocalist, she actually knows how to use her voice properly, whereas Christina evidently doesn't, hense her vocal decline
Although shes boring as hell she doesn't scream & over do it all the time like X-tina. Having said that when X-tina is NOT screaming she does very well too.
But when Xtina was in her vocal prime (debut album-stripped era) she would definetly take this. all of those years of oversinging really took a toll on her voice. Now all she does is sound a strained out screaming mess (no shade to the xtina stans)
