How do jpeg.io's proprietery JPEG optimization algorithms perform compared to JPEG2000, webp or re-jpeg ?

Probably well against JPEG2000, which isn't actually that good. Wavelets look bad when compressed because they blur so much.

JPEG will have a really hard time competing against WebP, x264 --tune stillimage, or HEVC. Nobody uses those though.

Great question. To the top!
