Hell's Kitchen simply because of Gordon Ramsay. But its become so scripted its losing its fun.
For my money the best reality show on today is Masterchef: Australia. The american version is simply horrible, the judges do nothing but try and outdick each other. But the Australian version is an actual fair competition between mostly decent people, and the judges seem to genuinely care instead of just trying to one-up each other.
