Being "machined" doesn't automatically make them better. "Stamped" threads are less likely to have errors in pitch over a machined screw.
That being said "stamped" screws are actually rolled onto the stock using a forming process that makes for tougher screw over all, as no material is actually removed from the blank. The actual hex is broached into the head of the screw regardless of how the body of the screw was formed. So there is no quality difference there either.
