From reporting on Harvey, I'd say Harvey response by far topped Katrina's response.

I was a 1st responder to Katrina in NOLA.  FEMA barred search and rescue efforts for days after the hurricane left.  Federal, state & local law enforcement agencies of the SE states were ready to respond before the hurricane hit & started towards or were already in NOLA the day after it hit. LEOs from around the country were also on their way.  FEMA immediately put out a stand down order to all federal law enforcement until FEMA decided it was safe to enter NOLA.  FEMA also claimed that those LEOs from the gulf states don't know the immediate needs of persons/cities that were hit by hurricanes.  DUH!  Our purpose Was search, rescue & to make the city safe.  NOPD had very few officers left to aid in this effort due to being stranded, killed, or just fled the city in the midst of the damage and chaos. & who knows more about the needs of hurricane victims than those who survived numerous of them.
