Really? I think Nicholas has a much better voice, his range is fantastic. Luke is really annoying, I think if he had a live band behind him his vocals would be lost. Wasn't impressed with him at all in big band week.
Sam Bailey is pretty awesome, I normally get bored with people on X Factor who do ballads every week but that woman is incredible.
I like Tamera, she's really talented, but very young. I think she'll be on fire in a couple of years time.
