As far as I can see, this debate hasn't nailed much down.

Yeah, I should've probably asked "what is the best mixer" because I've done nothing more than stir things up.

IBM used to outlaw Phillips head screws. There could be many reasons, but Phillips head screws are very easy to strip. Also, there are screw starters for slotted screws, but none that I know of for Phillips. Torx is the only kind I really like.
P.S.
I'll have to check out the Robertson. I forgot to mention that it is easy to fashion a square head screw driver with a file and almost any piece of metal.

That's a really great point.

As long as we've touched the waters of "in a pinch", I needed a small screwdriver to fix my glasses.
Not anything around . . . wait . . . a paper clip and a rock (hammer, etc.). Bang bang. Now we have a micro flat-blade screwdriver!

You know what? That's actually one of the best explanations of slotted still being viable.
Very cool.

The key to Robertson is the taper which square does not have.

Slot head screws are easier to take out when you don't have your toolbox with you. You can use the dumb little screwdriver head of your swiss army knife. You can use a nail file. You can use a kitchen knife. You can use a dime. Slot head screws are put there for people who don't spend a lot of time taking things apart.

One more note, based upon your "billions $$$ could be saved".
A few flat blade screw drivers will fit pretty much anything you find.
A little less so with phillps, but somewhat viable.
There are hybrid screws, as well, which take both flat blade and phillips.
For hex and torx? Another one for each and every size?
I think "billions $$$ spent" would be more like it.

Hmmm....I've created an industry.
Seriously though, I can agree with what you are saying.
That's why The World must agree upon one standard immediately and outlaw all other types.

"Reeducate those good-for-nothing lefties" who'd want to screw around with the direction in which we turn the screws.

You have way to much time on your hands.

These things must be considered!
And, I'd have more if The World would standardize on one screw type.

A plain-old bread-knife can replace a flathead or slotted screwdriver in a pinch, therefore making as the standard, in my opinion.

That does seem to be the best argument for it. Also people are saying it is far easier to fix a slotted head on a stripped screw.

A better question is, why hasn't everyone adopted Robertson.
Superior to both; invented in Canada; apparently "banned" in the US; something to do with "not invented in the US" I think.

My uncle (RIP), who was a strong union man, told me that the Robertson screw and screwdriver were banished by the unions because they were "an effective labour saving device".
I'm retired. There's a nap for that...

Thanks for that ... helps explain my continued struggle with the "irrational" (and products shipped with Phillips).
(And I "should" retire; but I'm not rational either).

I never heard that but what I did read is that Ford wanted to use them in their cars and have full rights to the design but Robertson refused to give it up.

Notice that all the screws in a mechanical wristwatch are slotted. There is a reason for this.
The original Phillips driver was designed for building aluminum aircraft. It was designed to cam out before the material being screwed into was damaged. Later cross-drive screws, e.g., frearson, were mostly not designed to cam out.
As others have said, with cross-drive screw heads the bit is self-centering. It isn't with slotted screw heads, but the slot is easily restored. If you ruin a cross drive head you need a screw extractor.
All the above are much inferior to Torx.

Fantastic explanation. Now the common camming problem actually makes sense. That's why it happens so much-- because it's engineered to happen. Thanks for the enlightenment.

Except for true Robertson, of course.

My main thought is that for every other type of screw, you need EXACTLY the correct size of screwdriver. So, for a general life, you need 6-8 sizes of Phillips, 8-10 of Torx, 4-6 of Robertson, but you can by with about three flat blade screwdrivers (small, medium, large). Specifically, in electronics, NO, I can think of no reason for a standard screw.
