Les would probably still have to deal with the loneliness issue, and would likely be amusing to watch babble into the camera (though I think he'd last a lot longer and handle it better, it's just fun to watch him treat the camera like Wilson). However, with the gear this guy was allowed, it'd be very much just an extended camping trip for Les.

As for which show I'd rather watch: I'd rather watch an intelligent, prepared person deal with the problems presented by the situation. I don't think there's an unoffensive way to say it, but this guy just struck me as weak-willed and more than a little foolish. I don't think he's the kind of person I'd like to be around in any high-stress situation.
