I like both Joe and Ollie, but for different things. I won't have either of their cds in my collection, but think they are both talented.
Ollie is a better entertainer, in my opinion. He is more fun to watch. But Joe has a better voice.
I think it would be best if Joe wins, because he more fits the mold of a manufactured "pop star" where Ollie is more unique and individual. He wouldn't be stifled by the molding process and would have more creative license if he took 2nd place. He'll no doubt get picked up, and will have more freedom.
Joes got all the pop star qualities. Looks, personality, charm, he's humble, and he has a commercial voice and would fit the mold.
All just my opinions o course.
But I wish em all well, whoever wins, hope they all get something out of it.
