Everyone has their own preference, but after 36,000km with up to ££££ worth of camera gear in it, I'll happily use Ortlieb again! There's also less chance of it getting damaged if you fall off / crash too (compared to if stored in a pannier or a backpack you are wearing) - and that is far more likely to happen than the cable breaking (for me at least! crashes 3 v cables 1!)
Just about any handlebar bag dampens the vibration. They are suspended and, being a nonrigid box, they don't transmit vibration all that well. A backpack would provide the same vibration isolation but it's not optimal for the same reasons listed above.
