First of all, the autopilot on US1549 was never engaged, so saying "the automation that day was worthless because it couldn't handle it" is pretty disingenuous.
Secondly, Sully's A320 remained in Normal Law (powered by the APU and RAT) throughout the ditching, with all flight control protections active until splashdown.
Great piloting yes, but he had some help.
Regardless of the "laws" he did not splash down with 13 degree ANU either did he? Do you think if that experience was on board AF447 it may have turned out a bit differently? I like to think so. Help or no help, he knows how to fly.
