Sometimes but with certain parameters AVIF can compete with Jpeg XL in photographic images at or near visually lossless quality even with the default "fast" preset 6. It would be nice if the devs made parameters like these enabled by default through a "photo" preset option.
avifenc -d 8 -y 444 -s 6 -q 84 -j 1 \
--cicp 1/13/1 \ # sRGB mainly used by PNG/GIMP
-a qm-min=0 \ # Forces max quality ceiling in super blocks.
-a deltaq-mode=3 \ # Psychovisual augmentation + speed boost.
-a aq-mode=1 \ # Enables variance boost.
-a sharpness=2 \ # Sacrifices some efficiency for image clarity.
