To My Fitness Friends Which Is Better Fitbit or Jawbone

Hey friends out there, I need your help in purchase a new fitness tool. I don't know whether or not should get a Fitbit or a Jawbone. Have any of ever used either one of these.

If you don't know what they are, they are used to track how many steps you take a day, how many you burn, and sleep patterns.

The Fitbit has a huge advantage, it's cheaper. They both seam to do the same thing, but is one better than the other.

I want to be fully informed before I get one! Please help!
