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.
Phillips is just common in consumer goods as it's designed to cam out when over torqued by the average joe. Better to have it stripped but tight than a broken head.
Still sucks balls when you know what you are doing though.
