I started out with the single cue and then my company switched to the crossbar one. In my opinion it is at least as precise as the other option, and it has the added bonus that you still have a director if one channel (lateral, vertical) doesn't work or is not switched on. Upon switchin from boeing to airbus the flight path director entered the picture and works as well.
