I love my Fitbit Zip but haven't been interested in either the Nikefuel or the Jawbone, although I've looked at them online.
My Fitbit has been the single best fitness purchase I have made in the past two years, it motivates me constantly to keep moving all day long. It works well. The iPhone app has had a lot of problems but they seem to have finally fixed it and it now works great for me. I can't say enough good things about it.
I think others may feel the same way about the other two gadgets shown. They are probably both very good.
It really comes down to what one likes, I think.
