Robertson isn't BAD in a vacuum, but if you're going to go to the effort of using a fastener that isn't as ubiquitous as philips or slotted screws, you might as well use Torx, which don't round out like Robertson.
Yeah, Allen wrench screws are shit.
Phillips was designed to cam out before the fastener broke. They intended for assembly line manufacturing before the advent of powered torque limiiting tools. Anybody that hates slotted screws more than philips has never owned a decent screwdriver and definitely never used a set of hollow-ground bits.
Phillips? Yes.
No, we just refuse to acknowledge square drive's snow-mexican heritage. Nobody calls it robertson down here. Basically all building wiring terminals made in the last 20 years are either phillips/square or square only because guys in lab coats figured out the average sparky would let the screwdriver cam out early and the connections would be undertorqued. It's such a problem industry standard is moving toward S2-only screw terminals. (jokes about limp wrists here)
Any screw head that will literally twist the drill out of my hand before it slips or strips is alright by me.
