Yeah, one of mine too, however I had a feeling he was all BS. Survivorman is a good one, he films it all by him self with many different cameras.. He doesn't do nearly the insane stunts Bear does, but it is cool learning about the skills to help you survive if you ever need them.
Survivorman is basically showing us surviving skills, while on Man Vs Wild, he uses his training from the British Special Forces, which very few of us, if any have. I have to agree that Man Vs Wild is more exciting though, he starts trying to get out the first day, not the last.
