Philips are designed the way they are so that they “cam out”. Meaning if too much force is applied to the screw, the driver will intentionally pop out to avoid damaging the tool or the fastener. Its a feature, not a flaw. A Robertson (square), torx, or hex will let you apply enough force until the screw or the driver fail catastrophically.

Maximum ugga duggas!
The Robertson, being a Canadian invention, appropriately allows the “full send” method of applying force.
As an American who has only worked with Robertson once, it was the best thing ever. Just so easy to work with. Even better than torx.
Built my deck w/ squares & it was way faster than any other type of screws I’ve used before.
Which is why Philips are so great for drywall screws. They shouldn’t be used to anything else though…
