Yuta Okkotsu killed Kenjaku in Jujutsu Kaisen.
What each of them is ranked on
The killer · Yuta Okkotsu · rank 4
Promised a girl he would marry her when they grew up, and when a car killed her the promise came back as a special grade tied to him for life. Handed Rika the whole of himself on the grounds of the school, and with his own sword already broken it was her beam that burned the right side off Suguru Geto. Took Kenjaku's head off later, then moved into Gojo Satoru's corpse using the transplant technique he had lifted off Kenjaku on the way past.

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.
