Anyone Thinking of Switching from Garmin Vivofit to Fitbit Charge HR?

I'm just curious. I have the Vivofit, but Garmin has so many syncing issues, it drives me nuts sometimes.

Anyone own a Charge HR and can give a quick review? I'm especially intrigued by the HR portion since it uses sensors on the wrist and not a strap.

Any help would be appreciated. Thanks.
