I like his show. He's a pretty cool cat, but I prefer "Survivorman" more. The voiceovers on "Man vs. Wild" are not my favorite, and while both shows are edited and all, "Man vs. Wild" is souped up way more. He also says a lot of confusing things in his shows. "I don't want to drink too much water, even if it's tempting to gulp", then in another show he'll say "Drink as much as you can".
"Survivorman" feels more like a documentary than a show.
They are both really cool though, and I've probably seen the entire "Man vs. Wild" series.
