v.surf.bspline, v.surf.idw and v.surf.rst are good for LiDAR and proven through various journal articles. I have found that v.surf.idw has as good results as these others with default parameters (only 2!) but is 10 times faster in processing. So if you don't have the time for v.surf.rst, idw may be the way to go for a quick or large map solution.
