Having tested both Torx and Roberson inset bits in a quality assurance lab, I agree Torx are superior. But the material strength and fit between the bit and screw recess are also major factors.
The 21 grams experiment refers to a scientific study published in 1907 by Duncan MacDougall, a physician from Haverhill, Massachusetts. MacDougall hypothesized that souls have physical weight, and attempted to measure the mass lost by a human when the soul departed the body. MacDougall attempted to measure the mass change of six patients at the moment of death. One of the six subjects lost three-quarters of an ounce. Wikipedia
