My favourite is Gareth because he just has everything a pop idol requires, and I'm sure he will win.
I think Will is an exceptional talent and will, I have no doubt be a huge star, although at first in pop, I think he will be more successful in a wider field.
Zoe again is very talented and will definitely be a popstar, she has the makings of a 'Diva' in the same vain as Aretha, all I can say is watch this space!
Darius is unique and different and has improved over the weeks, he will do well, but I'm not sure if he'll sustain a career in pop, but it takes all sorts so you can never tell!
All the remaining four have done incredibly well, even some successful popstars have been quoted as saying they would not have done even half as well if they had had to go through what the pop idol contestants have been put through, so hats off to them, and I hope they all do fantastically well, they more than deserve it.
