Phillips usually strip when using a pozidrive screw driver on them. Very common mistake because people think they are the sams, but easy to avoid once you know it.
Also, the fit has to be tight. If it’s loose, the screw driver is too small.
Posidrive is not that common and not the problem. Phillips heads strip because they’re designed to cam out and prevent snapping heads or overtorquing. JIS is same cross shape but doesnt cam out, which is good for avoiding stripping the heads but makes it easier to snap the head off of screws
Maybe in the US, but Pozidrive is very common here in Germany and other european countries in the form of “Spax” screws. They are the main screws we get for everything from wood working to wall mounts for pictures. They also don’t strip as easily as philips screws.
And trust me, I have seen plenty of philips screws beeing stripped ue to the use of pozi screw drivers while beeing perfectly okay when beeing removed with a philips screwdriver. Of course there are other reasons they strip as you mentioned, but here in Germany its a huge problem because Pozidrive is so common and people dont know the difference.
The reason for the stripping , that the shape of the tip is different.
Pozidriv drivers actually work very well on Philips screws, sometimes better than Philips drivers, due to the fact that the “vanes” are angled rather than curved, proving a larger contact area. Fit is definitely the larger factor, along with the quality of the screw metal.

They’re both junk next to Robertson though.
