I prefer r.surf.nnbathy, as I find natural neighbor or plain triangulation most robust for interpolating contour lines. However, these methods have their own problems - the output surface is not smooth (only partly - in case on nat. neigh.), kidney shape contours might be interpolated as plateus. But at least the result is predictable. If I want it smoother, I filter the DEM afterwards. But that's just me.
