We have the BRP CB system, which we use just for the intercom part, as we haven't yet ridden with anyone else who has a CB. So I can only comment on its use for helmet to helmet intercom work. While some people seem to have it work perfectly right out of the box, others seem to have some trouble with it. We fell into the latter camp, and although it's more or less working now, it's still not ideal. I can hear my passenger fine, but I have to speak pretty darn loudly for her to hear me. We've adjusted and twiddled all the controls, using info picked up on the forum here. In our case, since we were new riders without helmets, we got the BRP helmets and the comm system at the same time we got the bike. If you already have helmets, then one of the Bluetooth systems might make sense, given the potential difference in price (not that some folks don't seem to have issues with the Bluetooth systems as well, but at least there are several options there to choose from).
