APNG is at best a mixed bag, far from being a significant improvement over GIF.

GIF can have one palette per frame, which can be exploited to improve compression and quality (see https://gif.ski). APNG has to either use a costly true-color mode, which makes it compress worse than GIF, or one palette per entire animation, which gives it worse quality than GIF.

All the GIF-killer formats miss the point. They're trying to beat GIF on being primitive and inefficient, but GIF isn't successful because it's a dumb slow video codec, it's successful because it's old enough to be universally supported.
