To be fair, the Phillips-head (+) screw is designed to cam out (slip) when torque reaches a certain point. It was a workaround for dumb assembly machines in decades past.
These days, that behaviour is undesired which is why smart carpenters use Robertson-head (■) screws and electronics are generally assembled using Torx or Pozidrive.
The reason why flat heads were replaced with phillips heads is because machines would cam out on flat heads while it wouldn't with phillips.

Philips (+) keep the screwdriver from slipping and is designed to have it pop out at a certain amount of torque. You're supposed to pre-drill all the holes you need.
Robertson (??⬛) solves the issue of the screw staying in the drill, while keeping it centered, and you can still get at it if someone paints overtop. Reading up on it, the two reasons why it didn't gain popularity is because he got burned by a company in England and refused to license it, making it a shorter supply, meaning, Henry Ford, wouldn't be able to use it widely.
Torx (*) which is either 5 or 6 star, and like the name suggests, it provides more torque and results in less stripping so the sockets last longer.Last edited by profoundWHALE; 25 September 2015, 12:11 PM.

(Every dollar store screwdriver or $5 "entry level but made with decent materials" screwdriver you buy here has one or two slotted bits, two Phillips, and two Robertson, and so much else we get here is "take the U.S. version and slap a bilingual label on it" so it didn't occur to me that they'd be a local thing.)

Fsck a Phillips Head--people are dumbasses so they keep going once the driver slips out, and then you have to try and remove the stripped screw and replace it with a good one. Of course, a different head doesn't help...they do the same with Allen head screws, but at least they last longer. :/
