Nope. In my eyes AVIF is not more performance. It makes photos suffer and become blurry, especially so in highly saturated areas, skin, marble, vegetation. Once beautiful things start to look like cheap plastic.
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.
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
