The heroes (overall) are physically stronger - the villians smarter.
I think too overall I am voting for Rob. He is like Russell but with a boyish thing about him - that doesn't come across as offensive as Russell. I'd love to see Rob find the hidden idol over Russell.
I don't understand the Russell thing for hiding stuff and dumping out water and things like that - it just weakens his tribe overall in the challenges - I think it makes him feel superior that he has something over the others. And I wonder why no one suspects him? Don't they watch the other survivors? The minute that machette was lost, I'd suspect Russell.
Not sure who I like best over at the heros camp - but one thing I don't like Rupert as much as everyone else seems to be - he seems a bit wimpy to me. Right now I have no favorites at the hero camp.
