We stayed for two weeks in December during some of the problems on the French side.
The Dutch side has made great progress. Yes, there is still far more to do (removing the partially sunken boats or the ones stranded on dry ground)...but as others have said, that was one massive hurricane.
The biggest issue I see is the airport. The fact that it has taken this long to get to this point is ridiculous. In 2018, there were insufficient seats on the floor and we were sitting on the floor. At least in 2019, there were sufficient seats.
We arrived three hours prior to our flight time (as advised) and were told that they couldn't accept our bags yet and to wait an additional hour. We had to stand outside waiting.
Our arrival in SXM, we had to stand in line an hour to get through immigration. Some of that was outside.
We were considering an additional trip in February 2020. But I think I will wait another year to see if anything gets fixed at the airport.
