Check the file size - anything will look bad if you set the compression too high. If you see AVIF images with some artifacting, find a JPEG of the same image and compare file sizes. An AVIF the same size as a JPEG will be better than the JPEG - an AVIF only 50% of the size will probably be visually undetectable to most people. An AVIF only 20% of the size... you'll tell. Same for JXL - if I set my JXL to compress to only 15% of the size of the JPEG, it's hardly a fair comparison.

For my eyes: AVIF fails to deliver a consistent experience at 3+ BPP -- I'd hate to compress my family pictures at AVIF even at high BPP, some part is smudged in a weird way. libjpeg-turbo and mozjpeg does deliver a consistent experience at 4 BPP guetzli and jpegli delivers a consistent experience at 3 BPP JPEG XL delivers a consistent experience at 1.7 BPP
