Which of the three gear effects turned out best?

I wasn't sure which idea to make on a larger scale, so I setup three of the ideas I had.

The first effect is edited, there is a break when the blue ring didn't fall (I forgot to put that at the end)

I don't know what to call this....any better title suggestions?

I am not part of CDT 2012 or Domination 2012 events, but if you haven't seen them yet please go watch their setups:
