JPEG and JXL have the benefit of (optional) progressive decoding, so even if the image is a little larger than AVIF, you may still see content faster.

Note that JPEG XL always supports progressive decoding, because the top-level format is structured in that way. The optional part is a finer-grained adjustment to make the output more suitable for specific cases.
That's great, are there any comparison graphs and benchmarks showing that in real life (similarly to this article)?
A couple of videos comparing progressive decoding of jpeg, jxl and avif:

There's more on the same channel, generation loss ones are really interesting.
Awesome, thanks.
