So you don't trust what we were told, even if we were told Moria lost to Kaido only becuase of his weak crew.
Then, stop pretending that Shanks beating Loki (It was said captured, but let's say beating) It's some unavoidavle, objective truth.
The manga Is full of people reporting one thing and then the actual truth was the opposite. Until we saw Shanks vs Loki, we don't know what happened.
If not, as we say Shanks > Loki, we have to say prime Moria ~ Wano Kaido because of what we were told.
