The Human World Treasure List ranks the Law Lotus Platform eighth, Ksitigarbha's True Body tenth, and the Purple Green Double Swords seventeenth.
Typically, people in the Immortal Cultivation World consider the top ten as a tier, from eleven onwards to be the second tier, and anything outside the top thirty to be another tier... As such, there was a distinct difference in rank between the Purple Green Double Swords and the first two divine artifacts.
However, this doesn't mean that a higher ranked divine artifact is superior in all aspects.
For example, the Seven-Star Divine Sword ranked at number two, compared to the first-ranked Demon Suppression Tower, certainly doesn't possess the unparalleled power of suppressing the Ninth Realm. But if you measure the destruction caused by a single attack, the Demon Suppression Tower is still inferior to the Seven-Star Sword, which is a pure offensive artifact.
