In the auditions/boot camp stages I liked both Cassie and Rowetta.
Cassie is now my firm favourite, her two performances in the live shows so far have been sensational

, but I have gone off Rowetta slightly. I thought that both of her live performances have been average, unlike some of the brilliant powerful performances she gave earlier in the show. I think Simon may be picking the wrong songs for her - her voice is not coming across very well.
I also like 2 to go - their friendship makes them come across very well as a duo. They both have brilliant voices but I agree with Louis that I'd like to see them do more "modern" songs.
I was indifferent to Tabby during boot camp and auditions - he reminded me a bit of Benji from Good Charlotte

- but he has grown on me. I now think that he has a very good chance of winning the show.
VWS- I love their voices - but their personalities spoil it! They can be OTT and rather selfish. When Roberta was voted out and one of the VWS girls pushed her away when she tried to hug them - I thought that this was out of order. Their OTT reaction to staying in was ridiculous.
Steve - did not stand out to me in auditions or boot camp - he is average and rather boring.
G4 -

They sound terrible! They completely murder great songs and the facial expressions they pull - look like something out of Scream!
