The JIS is basically a Phillips with a shorter point. The are a lot of other detail differences, but the one that matters the most is the length of the tip. If you have a JIS screw, you cannot get a Phillips in deep enough to engage properly, and the Phillips can rotate without the screw and sometimes strip the head of the screw. The JIS screwdriver head will fit deeper into the JIS screw and turn the screw without slipping. The JIS screwdriver generally fits better in a Phillips screw than a Phillips screwdriver in a JIS screw. There is an even pointier version called a Reed or Reed and Prince screwdriver that has the same problem in a Phillips screw that a Phillips screwdriver has in JIS screw. A Reed and Prince screwdriver doesn't work at all in a JIS screw.
