Some claim to have stripped Robertson screws but to be fair, the metal used and amount of torque the peson applies is the biggest reason for problems.

Phillips heads were supposed to solve the over torquing problem, but everyone didn’t listen to standard specifications and didn’t bother using them as they were meant to be made and used. The Philips head was supposed to slip once the correct torque was applied. Unfortunately, this positive benefit became a negative. With poor metals and a mismatched driver bit to screw head along with not using the screw head that was meant for the specified torque demands, the Phillips screw became known for stripping.

Trying to implement non overtorquing feature to the square bit and you will find how similar it will look to the Phillips head.

Right now, Torx is the best at not stripping, but good luck if the screw is overtorqued. Eventually, the cheap metal gives out with the screw head, or bit, snapping off.
