The BRP in Virginia is not spectacular to drive but it is substantially less crowded. This probably has something to do with the population densities of NC versus VA (I expected App state and Boone to be a deserted college town like Harrisonburg VA or Clemson SC). However, the roads leading up to and intersecting the BRP in Virginia are very fun for at least a few kilometres.
VA 684 Reeds Gap Rd. in Augusta County
US 60 in Rockbridge County
US 501 in both Rockbridge (VA-130) and Bedford County
VA 43 in Botetourt County, the very last hairpin is incredibly steep- many scrapes on the road. (It's not the curve in this picture though)
There were a few fun spots near Boone; I tried US 221 but the curves were in a semi-residential area with too much traffic. NC-194 had a few good curves but once again, too much traffic, and the road was not smooth.
I will admit that WV has some of the best mountain roads because they engineer "truck" lanes and larger banked areas on the mountain passes, allowing one to get around slower traffic and/or do higher speeds (read: sliding burnout). The gradients are also clearly marked, similar to NC. In Virginia, there are no overtaking lanes, turnouts or widened hairpins, and no gradient information.
