What's the difference between pansexual and omnisexual?

Both "omni" and "pan" mean all, so as a result, pansexuality and omnisexuality are both the attraction to all genders and sexes. They are synonyms, although pansexual is used more frequently.

Pansexuality and omnisexuality are attractions to all gender identities and sexes.

So No difference. It’s all post-modernist garbage nobody reasonable should bother thinking about. The more time you waste pondering this, the more the people who invent this sort of language win.
