It's actually pretty hard to say - The Apprentice is by some margin the best editted pre-recorded reality show. It does a wonderful job of not making it obvious who is going each week, or which team wins.
Last nights episode for example: Even though the girls had a clearly superior product, they showed the boys selling a lot more, making a huge question mark.
Plus, of the boys team, at some point in the episode and the boardroom, I thought each of the final three would be fired. In most other shows they feature heavily on that nights eliminee, giving it away well in advance.
