River hill, Marriotts ridge, Glenelg if you can afford to live out in west county, less risk of redistricting due to those schools being less crowded. Centennial/hebron are also great schools. Below that I would say Atholton/Howard are also nice. In Howard county it’s all about wealth when it comes to schools, the better the schools rank the more expensive it is to live in the district and less affordable housing (apartments) or none at all.
