AVIF is a mess from a technical standpoint. designed by committee. it doesn't just store a straight up image, no no no. it splits the image up into chunks, each of which can be stored using any codec supported by the format. this is a huge hassle for the internal data model for many project, for example ffmpeg
WebP is OK, but getting support for it everywhere seems to be slow going. I'm not convinced it's sufficiently better than cjpeg to justify widespread use. JPEG itself has many features that improve its compression that no one uses for some reason. like pyramidal coding

to elaborate on this:

>Mozilla has done a study of image formats and concluded that WebP and JPEG XR are not a big-enough improvement over well-optimized JPEG. In the study only HEVC (H.265) was significantly better, but it’s a patent-encumbered format, so it can’t be used freely (shhhh!)

webp seems ok to me. I guess avif is technically more fancier, but it has no support. both can do lossy and lossless so that's not an issue

It just werks™
