The only real reason for Phillips screw heads were the old electromechanical industry robots that would rely on auto-centering and spring tension to pop the driver out of the screw against a switch at the set torque. Modern (since 1980s or so) industry robots are computer-driven and torque-sensing. Phillips (and Pozidriv) needs to die in favor of modern superior screw drive designs like Torx.

Out of interest what is better about Torx?
With "normal" screws you can usually improvise something when you are without tools.
You can usually "improvise" with a torx using a flat head screwdriver - it it locks in place it will turn.
They don't strip, or at least it would take a tremendous amount of torque to strip them. My experience has been that the driver strips before the head does.
That stripping the driver before the screw is a feature. Heads come with every box of screws I buy, and getting out ruined screws is far harder than replacing the driver.
Usually the screw snaps in two at over-torquing before either the head or tool strips.
I've had that happen a few times. It's super annoying, but that what you get when not paying for the quality screws.
Happens with the better ones as well, it's just a matter of setting the torque limiter of your screwdriver/coordless drill to match the job. Sometimes takes a few mistakes, but it's safer to start with a low setting and adjust up until you have the right torque for the screw.
