LOL sure, good one... Only time robinson is the answer is if the question is "what do you get if you put a toddler in charge of designing a poor knockoff unbrako head?"
I'm not canadian, so I don't have a lot of experience with robertson. But from the limited experience that I do have, I would rate it 10/10.
What would you recommend for smaller screws (e.g. for electronics)? As far as I know, there aren't smaller sizes of robertson like there are with torx?
I’ve driven tens of thousands of pozidrive 2/3 screws into timber with an impact driver. For whatever reason my experience is the diametric opposite of yours.
Big up the Pozidrive massive.
It's probably because of the impact driver. The bit seats back into the bottom of the slot between every impact. This doesn't happen with normal drivers.
