WebP is awesome at lossless and way better than even PNG.
It's because WebP has a special encoding pipeline for lossless pictures (just like PNG) while AVIF is basically just asking a lossy encoder originally designed for video content to stop losing detail. Since it's not designed for that it's terrible for the job, taking lots of time and resources to produce a worse result.
On the other hand, animated webp is surprisingly bad considering that the format comes from a video codec.

I mean it's kinda hard to be worse than just shoving a bitmap through zlib...
