I think it would be avif. WebP can't compete with jpeg-xl in terms of feature set. But compared to avif, jpeg-xl allows seamless transition to jpeg (for compatibility), progressive decode, higher bit depth HDR, and ability to use common encode/decode pathways with jpeg.

Right. In terms of pure bit rate, jpeg is awful, webp is better, and avif and jpeg-xl are better still. The thing is that avif has a lot of weird quirks due to it being a hack of a video codec: AV1. JPEG-XL is a much better image format just in terms of feature set, definitely better for high quality images. I use avif because it was out first, but I planned to switch to jpeg-xl once browser support was better.
