The later cast hub would be the way to go, CNC billet hubs get stress risers from the cutting tools leaving valleys. Look at the cracks, they follow a tool cutter valley for a distance, make a sharp turn over the ridge before following the cutter valley again. A smoother surface with out stress risers combined with the thicker material around the spokes looks to be why there are no examples of later hubs failing.
