SU800 vrs SB900
The flash has to fire to set of the IR pulse to trigger other flashes.
Therefore the downside is if you have a 'blinker' for a subject you run the risk of many shots with closed eyes :/
Upside is you can use the on board 900 for a bit of fill-in if you so wish
Light is Light, its what you do with it that counts
