I have a Bodybug and a Fitbit. In early June I did a week long experiment where I wore both all day and night and used my HRM for exercising. The numbers were virtually the same, with the Fitbit actually coming closest to matching my HRM. I wasn't doing CLX at the time but have read in several places that none of those three measures accurately when doing strength training. I do set my Fitbit to record an exercise activity before I do the CLX workouts and edit them on the Fitbit site to give them a name.
The Fitbit is smaller, not at all noticeable, and the free access is all I have. I did not like the cost of the BB and I hated the look on my arm all the time, especially at work. Even short sleeves don't cover it sometimes. I teach 2nd grade and got tired of answering the questions all day! When I stopped wearing it in Feb when I got the Fitbit it was because the BB had caused an irritated spot on my arm.
My $.06 (adjusted for inflation!) is that the Fitbit is the way to go.
