The Sorcerer Killer
Carried no cursed energy whatsoever, which left the sorcerers' usual means of spotting a threat nothing at all to read, and kept his cursed tools inside a curse he used as luggage. Put a blade through Gojo Satoru and shot the Star Plasma Vessel dead on the same job, having already arranged to hand his son to the clan that threw him out — a sale he announced and never completed.

The Star Plasma Vessel
An arrangement gets written with her inside it as the item changing hands. One body designates her; another pays to stop the transfer; she is asked by neither. She says she would rather spend more time with everyone, and is shot dead before the merger can happen. She is the object of the deal and never a party to it, which is not a position a ladder of parties has a row for.

What this does not settle
One death in one work. It is the only place the record puts these two in the same room, and it is evidence about that meeting and nothing wider — not a general matchup, not a rematch, and not a ranking of its own.
The ladder above it is argued from everything either of them has been shown doing; this page is argued from one citation.
Where the two disagree, the disagreement is the point, and it stays visible rather than being resolved by whichever of them happens to be on this page.
