It is my opinion that many folks confuse the metaphysical state of one's soul with its current or potential future position / rank within God's Kingdom.
Mary's current state IS that of an angel right now - just like all not currently in the flesh. She wasn't an angel, state-wise, when she was in the flesh. But that state itself does not make her 'better' than you or me in a rank/position sense.
However, she IS better than most in the sense that she earned a high rank via uncommon faith in this age and presumably in the first age.
Though it is a sin to worship her. Or any 'angel'.
If you are faithful and overcome, then you too will be superior to many angels. Including better than one archangel - Satan.
