It really is the greatest bigly standard of all time. Phillips is just stupid all around. Flathead? No thanks.Pretty much the standard in Canada.
Phillips are for bitches.
And there are only a few sizes really. Why does every shitty bit set come with 28 phillips bits?
Greatest things of robertson are the low chances of rounding it out and being able to stick the fastener on the bit and it holding without a magnet.
