- In my own testing JPEG XL demolishes AVIF and WebP in terms of bitrate at my desired quality, particularly for artifacts around sharp edges. - This can (in theory) be solved in other formats by improving the encoder, but the current jxl encoder is pretty much "set it and forget it" in terms of getting a good quality; other encoders are far more variable (e.g. I would use a different quality setting for B&W vs color and line-art vs photo). - In others' testing (I don't use this feature) JXL has better lossless compression.
