I'd say you're probably right about Bradley and Sarah.
As for the rest, I would imagine Josh and George rate closer to the top because they're the kind of big softies who normally win.
I'm quite confused about Ben. He appears to evoke strong feelings in people and on these threads they're mostly negative. But then he stirs things up, so I suspect might be appreciated for entertainment value.
As for the others, I just see them all somewhere vaguely in the middle.
