Consider the fact that "other reality stars" (e.g. Charlotte Crosby & Scotty T) won their years and I think Ekin Su is probably a good bet, unless she turns out to be particularly boring or awful. But even then, Scotty T wasn't exactly entertaining, sleepwalked through most of the show and still won.

Louis Walsh won't win by all accounts he's a bit of a dick and that will inevitably come out.
