Good drills that crew
The captain's perception to ditch somewhere the chances of immediate recovery are high is to be applauded.
I'm not a pilot but the ditching appears to have taken considerable skill - getting rid of the energy whilst not stalling takes real airmanship.
Cabin crew orgainsing an orderly and panic-free disembarkation is risky conditions is no mean feat. I would imagine that the immersion survival time in the Hudson in this time of year is not much more than a very few minutes.
Trebles all round!
