It sounds as though Robertson screws/screwdrivers are hardly ever seen or used in the US, though they're very common in Canada. And from experience I can tell you the Robertson is far and away better than either slotted screws/flat blades or Phillips screws/screwdrivers. They just work better during assembly and even more so on disassembly. The screwdriver needs very little forward pressure to stay fully engaged and for the most part just doesn't slip.
They work well in all sizes, and it's fairly easy to insert a Robertson screw with one hand when used vertically and even to a certain extent when used horizontally (as the screw balances readily on the screwdriver).
This might even be an important business opportunity. Once people have tried a Robertson screwdriver, they won't go back to a Phillips.
