x2. From what I've read, the phillips head was designed to cam out at at given torque, possibly since torque limiting devices weren't around. The posidrive (very similar to phillips) came along to minimize cam out. But square drive or Torx are far superior drive mechanisms IMHO. I only buy phillips/posidrive if Torx or square drive isn't available.
Also, many of the Phillps/posi drive heads I've seen are really a combo square/phillips drive. Look carefully at the center and you'll often find the center is designed for a square drive.

Jet, not quite true "A screw is a screw" There is no such thing as a bad screw, but some are better than others

The reason they are so widely available in Canada but more difficult to get in the US is because the patent is held by a Canadian company.
The Robertson company invented and patented the square drive screw.

One screw is not stronger than the other. Square/Robertson drive have less chance of stripping the drive when screw is tightened or removed.
I fully agree, there are basically 4 screw types I use here
Straight (slot) Phillips, robertson and Torex.
Robertson fit on a square driver or a robertson drive, on a square drive they will remain on the drive while I use the screwdriver to bring them to the point where I wish them to screw,, Same with a Torex, Plus I can "Reef" on the screwdriver fairly well and it won't strp the head.
On phillips I can not tighten as much, and they will fall off easier
Straight I can tighten a bit more than Phillips (usually) though not as much as square, and less I use s apecial spring loaded screw starter they WILL fall off, guaranteed.

 Sheeesh, we're trying to send you our oil and can't get it through the hoops, what chance does a small screw have?

I carry about 20,000 of them at any one time in my truck. How many would you like?

Phillips head screws were made in widespread use in the US because Henry Ford realized that they cam out instead of the head breaking off when his vehicles were assembled.
IMHO, Phillips head screws need to be phased out. There are far better designed out there which are far more resistant to stripping, transmit more torque, and require less screw material on the heads for engaging. Robertson is a good style. Torx is another.
I wish square-head stainless steel screws were more common. I had a box of them sit outside 20 years in a trash can, and they still look as good as new.
