GU refers to Marquis' shard as a "common craftsman" while giving Amy a royal title, so Marquis probably has the lesser of the two. Scion was a combat focused Entity containing trillions of shards, so he's going to have a frankly ridiculous amount of redundancies spread out between the sheer number of shards and the expectation of combat damage. QA is often regarded as his most important shard, but while it was his primary administration shard, he probably had millions of lesser administrative shards scattered through out his bulk like we have nerve cells in our bodies. QA was just his equivalent of a brain stem.
