Not only is it self-centering like phillips and JIS (eg the reason they are used in so many line-assembled manufactured goods) but it's has superior contact like a Robertson (square drive) or hex or torx.

Torx's highest-in-class leverage without camming out gives it superiority in some applications (eg impact-rated deck screws), but if you had to choose one fastener head for everything, posidriv is it.

Torx is not self-centering, and therefore inappropriate for many tasks including anything not hand-assembled. It is also susceptible to stripping out after rusting.

The patent is expired and it now has ANSI and ISO standards.
