Best advice I have seen so far is to go visit and see for yourself if possible. Only thing I would add is, if you have children, go to a park with them on a Saturday and see how it feels. When I've taken my kids to the large, gorgeous Ft. Foote park, its been an absolute pleasure. Well behaved kids, friendly parents across the board.
I am AA grew up in Ft. Washington, attended private schools, and am moving out of the city (Capitol Hill) to raise my family there. The area close by National Harbor is lovely, safe, quiet and easily accessible to DC and VA. No whole foods or trader joe's, but shoppers food and safeway are fine by me for the basics, can do TJs in Alexandria or Wegman's in Woodmore now and again.
With the new outlet mall, there might even be too much shopping in Ft. Washington now
