For many years now, I have always used the black handle Xcelite Phillips

Isn't the issue that there is some Japanese variant of the Phillips
screw, called something else, so while nominally a Phillips fits it,
it's not really a match?

Are you thinking of a pozidrive screw, if so a Phillips screwdriver
shouldn't be used.

Alas, it's not that simple. Pozidrive is licensed by Phillips just like Phillips is,
the Japanese use JIS standards instead.

Frearson (aka Reed and Prince) is a fourth standard; that one, rarely slips
and doesn't have multiple sizes with different shapes. It's rare, though.
