Ahhhh....Do you think?
Possibly an extremely large storm that hit a poorly prepared and vulnerable area of barrier islands and sea coast areas, but not super at all. No 200 mph winds for 2 -3 days, no 30 - 40 foot storm surges, just a big storm, not frequent, but inevitable. In many aspects, just like Galveston, TX where it gets completely washed away every 100 years or so .... completely washed away .... everything, but they rebuild it each time at great expense ignoring the obvious stupidity of it each time. When you live on the ocean, below (New Orleans, subways, etc.) or at sea level, you are going to periodically going to be destroyed....not maybe, you will at some point.
NOBODY has that kind of winds speeds for that kind of time frame.
If that's your criteria for making it a super storm, you;'re way out of step with reality.
Those who didn't live through it can poo-poo it all they want but all they end up doing is demonstrating how out of touch with reality they are.
That storm and the situation that spawned it was so unprecedented that it well deserved being categorized as a superstorm.
