What each of them is ranked on
The killer · Satoru Gojo · rank 2
Limitless and the Six Eyes in one person
Received Limitless and the Six Eyes at birth and paid for neither. Went through the curses and transfigured humans filling Shibuya station on his own, and finished Suguru Geto himself after a first-year's curse had already burned the right side off him. Was folded into the Prison Realm in the seconds his own eyes spent refusing to read the face walking towards him as anything but the friend it had belonged to.

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.
