If this years contestants were in past series ...

[Tom]

who would do well?

If Ruth entered last year she would have had Sharon Osbourne as a mentor and I think she would have wiped the floor with the rest of the acts (bar Rhydian), and could have beat Niki to the top female spot, if not won it.

I think Rachel also could have won it last year if Louis gave her the right song choices.

[Locke.]

Well last year was the weakest of any of the music reality shows that i've seen so I'd say pretty much all of them would be in with a shot (apart from the obvious ones.)
