What is the advantage of a Phillips head screw?

What are the disadvantages of a Phillips screwdriver?
One of these drawbacks was the tendency of slotted drivers to over-torque a screw. The Phillips screwdriver was designed to purposely pull-away or "cam-out" when the torque becomes too great. This prevents the screw head from snapping off and also allows the operator to know when the screw is fully seated. via
How do you maintain a Philips head screwdriver?
Which is better pozidriv or Phillips?
Phillips screw heads are designed so that the Phillips screwdriver will cam-out (slip) if too much torque (power) is applied. Pozidriv screws, on the other hand, are designed specifically so that the screwdriver head does not cam-out. Phillips screwdrivers fit in Pozidriv screws, and can turn them. via
Why is it best to use the right size of Phillips type screwdriver?
The most important technique is to use the right size screwdriver. Phillips head screwdrivers are designed to “cam out”, which means they are designed to slip out of the screw, so you don't over-tighten them. This also leads to their greatest pitfall. via
What's the difference between PH and PZ bits?
PH is short for Philips head, whereas PZ is short for pozidrive. PH screws just have a cross slot on the head; PZ look similar but have additional lines between the slots. The 1, 2 and 3 signify the size of the screw slot. via

What is the difference between flat head screwdriver and Phillips head screwdriver?
A newer variation of the flat blade screwdriver uses a cross drive system and is commonly called a "Phillips head screwdriver." These screwdrivers have a 123-degree point with a blunted tip and tapered cross-shaped blade tip that provides self-centering on the screw and is designed to prevent over-tightening of the via
What is the difference between a Robertson and a Phillips screwdriver?
Robertson's design consists of a tapered square-tipped screwdriver that fits into a matching square recess (the "socket") in the screw head. This design makes a Robertson screwdriver less susceptible to cam-out than a Phillips driver because the driver bit inserts deeper into the screw head. via
