I am using Orion on Mac and iOS for a few years now and I cannot disagree more.

If a site works on Safari but not on Orion it is mostly due to ad blockers etc. Just flick the compatibility mode and it works. I have not encountered a single case where this did not fix it.

Also for a while now Apple Pay works, Apple password manager works, autofill works.

+1 - using Orion on iOS & MacOs for a few years and i like it!
