I have not experienced chatterbox, but have used scala Q2 and blueant intercom F4.
scala is nice product. The blueant disconnects from the friend when she gets more than 400 m behind and it doesn't reconnect apparently the scala system will still reconnect and battery life lasts a hell of a lot longer.
also above 65-70, my blueant F4 starts annoying noices, so it becomes impossible for me to enjoy music or stay connected withl riders. Its just a useless device for me. so I would recommend scala to every one.
