If im correct then I believe the 777 is FBW but even so this is not relevent.
As to the comparison of the Hudson incident and this one Im not totally convinced that they can be compared due to the circumstances.
Two different stages of flight, two different configurations, two different aircraft and more importantly two different surfaces on which they landed.
With regards to the stall situation, I believe it has already been stated that the impact is regarded to be at relatively low velocity and there for a SHORT ground run. As for spinnig, with full flap and LED's deployed I believe the spin is highly improbable.
