I still believe Olly should win but even if he comes 3rd his career is assured as he's pretty unique and likeable with a good voice.
Joe stands a great chance of winning as he is a perfect X Factor pop star. Always smiling, consistently good performances, great voice - in fact the best voice. I'd still choose Olly personally but Joe could win this absolutely. He can be moulded as he's young into whatever they want him to be - and if he didn't win - then same as Olly his future is assured.
I do like Joe there is nothing to dislike about this young man.
