I've worked with Geomagic Studio many years ago for handling point cloud data from human scans and sets. At the time we tried Paraform 3d(don't think it exists any longer) and Rapidform : It was precisely in the most complex circumstances that GS was out shining the others(particularly in repairing fine defects after the tessellation, like overlapping surfaces and inverted normals). Also it has a very high quality system for converting the point data to nurbs surfaces/subd's.
