Comparing devastation can be a bit misleading as the hurricane that impacted you personally would be more devastating to you. It might make some to feel that their suffering is being ignored.
Katrina flew over FL as category one, strengthened to category 5 as it moved across the Gulf of Mexico and wakened to category 3 before making landfall. Sandy hovered between tropical storm and category 1 hurricane. East coast is populated more densely and real estate is more expensive here. Monetary damage due to Sandy might exceed that by Katrina.
