ALEXANDRA IS THE BEST
IF U THINK ABOUT IT SHE'S THE 1ST ARTIST TO PROPERLY BANG OUT ROUTINES AND SING EACH WEEK.
I haven't seen that in American Idol and rarely in X-factor as many times as Alexandra has.

She's not even that kind of performer usually but still puts it out there week in week out.
She's singing on key and dancing thats impressive. A true performer.

Diana has a unique sound but thats all she brings to the table. Compared to Alexandra she hasn't been the ultimate consistant performer and thats not being looked at.
Although i say this i do like her voice and thinks she has alot of talent and alot more in her vocals to come out
