I thought the whole “JIS is different from Phillips” thing was a misunderstanding and JIS is just a type of Phillips or something and it and “regular” Phillips are more or less compatible
I have this iFixit guide as my source: https://www.ifixit.com/Guide/Choosing+the+Right+Screwdriver+Bit/93991#s176809
According to that, the JIS screws have orthogonal inner angles, while the Phillips’ are rounded, resulting in the slipping bits.
However, some Phillips screwdrivers fill out that space, and thus won’t fully go into a JIS screw, and effectively be too small, stripping it.
