With Robertson, the screw will stay on the driver so you don't need to see it to find it.

Can do that with any head really. But imagine the screw is there already. And you don’t know the size. Phillips is probably better here. Not a common use case for most people.

I've never been able to get a Phillips screw to stay on a Phillips screwdriver. If you do get it to stay, a butterfly flying by would knock it off.
