Pozidriv is clearly superior to Phillips
-
Why?
-
It was designed to allow more torque to be applied and greater engagement than Phillips drives. As a result, the Pozidriv is less likely to cam out.
-
IIRC that was a design feature of Phillips screws, not a flaw. Deliberately designed to limit torque to avoid over-tightening.
-
Interestingly, it was an accidental feature. The original patent application makes no mention of it, but 9 years later they added language about it camming out to the second patent application. https://en.wikipedia.org/wiki/Cam_out
