They're filmed at the same location and use much of the same missions - only difference is the US one is a couple of episodes shorter and full of reality stars.
It was certainly worth watching both last year and I think it's the same so far this year too - the US one is very good, but the UK one is just on fire this year. Everything seems to have aligned perfectly for them and tonights episode has set up the final week perfectly.
