Sully's wasn't gentle either. As against recommended ditching of minimum VS, Sully landed around 740ft/mt. That's because of the time pressure his speed went19kts below recommended Vapp and due to activation of airbus alpha (low speed) protection was unable to flare sufficiently. That's why aircraft was written off.

Any airliner that goes into salt water is going to be a write off. Almost certainly the same for fresh water.

I see TE flaps in, or almost so.

Imagine a crew trying to make a field with insufficient thrust, understandably they'd be keeping clean conf. and speed for max L/D. On the other hand, a pre-determined ditching is surely flown at the slowest Vref you could get.

Estimating 210 and 130 kts for the two cases, with an impact weight of 49 t,

the kinetic energy equation gives 270 MJ and 104 MJ respectively.

No need to look any further why the same metal buckles and bends once but breaks and tears on a different day.

The involuntary ditchings discussed above were all at approach speed, to my understanding.
