I tend to watch all of the competition shows (chopped!!) and not as much the more basic, recipe centric shows, so i think it's much more about cooking and skill to me than my own hunger. i love to bake and have learned a lot of tips from some of the shows so it's been a great tool for me.
Chopped is my favourite too! There's even more chopped on now that there is Chopped Canada. The shows Diners Drive Ins and Dives, and You Gotta Eat Here are just terrible. They just showcase the unhealthiest food in North America. Chopped shows real skill and finesse. It doesn't even make me hungry since I see it more as art than food.
