Virginia has a much lower violent crime rate (104 per 100000 vs 977 per 100000 in DC), lower taxes, a better social scene, and is more accessible to any of the common recreational activities (hiking in Shenandoah, camping in West Virginia, wineries, breweries, etc.).
Even if you like going out to a bar to socialize, I still think the Clarendon area on the north side of Arlington is better than literally anywhere in the District.
