In terms of picture quality for given size, AVIF has it solidly beat.

You could make an argument that we should have AVIF everywhere on the web. But if you want a single image format to be everywhere, I think JPEG-XL is just better suited. AVIF has restrictions on resolutions and number of planes, and doesn't do lossless very well. It's competitive with AVIF on lossy image quality (even though yes, AVIF does seem like it tends to consistently have the advantage there).
