The tapered fit is the reason, and the article outright dismisses this and claims it "increases cam-out". Even with a worn bit, pushing a screw onto the bit means you can grab hold of the screw and swing the drill around. In practice, (especially with impact drivers), the bit seats myself in the screw so thoroughly that you will break the head off the screw before it strips.

This is exactly the reason I love Robertson. You can install screws one-handed or in hard-to-access areas very quickly because the taper locks the screw to the driver. Torx and hex drives don't have this important feature.

Here is video showing how Robertson stay on & straight VS Torx falling out easily: https://youtu.be/PMXOTRVYNiw?t=206

Not to mention that there are technically six Robertson head sizes, but 90+% of screws are #2 and basically nothing uses any sizes other than #1 and very occasionally #3.

I get tired of needing a bit box with 10 different torx sizes so I can find the right one.

Why aren’t magnets used more to achieve the same effect?
