I'm interested in the topic, because I do believe that all the pagan cultures had some flawed awareness of God the Father, inherent to our souls due to being his children. Remember Acts 17:23 and the monument to the Unknown God at Athens.

If you look at the roots of words like Jupiter, Dyeus Pater, "Sky Father", you see cognates all throughout Europe and in the peoples of the Indian Subcontinent. I don't think we need to bother with any sort of autistic "ranking", anything short of the fullness of the Truth is short of the fullness of the Truth, and it seems practically every culture on Earth had some conception of God the Father in their own flawed way, with many even having similar messianic stories. This is why we can say all of paganism was an anticipation of Christ.
I believe that even though the Israelites in particular were chosen by God to usher in the Messiah, all the peoples of Earth, or most of them anyway, had some form of understanding within their souls simply by way of being children of Adam that God the Father exists and is the supreme God who would come again. Remember, even the Israelites took time to develop the understanding the God the Father isn't just the supreme God among many, but that he is the only God. Their conception of him was disordered before his continual revelation as well. So why try to rank the pagans and the other religions? They all practiced according to their understanding, according to what was revealed to them or whatever they knew in their souls which had been corrupted over time.
I'm sure there are many flaws in this assessment though, as I am smol brains.
