Well, it depends on what you plan on using your BT headset for.
Most people love the Jawbone sets, and if you're just looking to use something for phone calls, its hard to argue a better one.
Personally, I use BT for music / listening to lectures more than phone calls, so a stereo set was more important to me. Also, I sometimes ride a motorcycle and want something that could have an external speaker wired up to mount inside my helmet, while keeping the controls and mic down where my mouth is (on the neck strap).
I *DO* realize that I'm not normal. Most people aren't trying to do what I am, so I would just go with the Jawbone. Its not cheap, though.
