What each of them is ranked on
The winner · Sho Suzuki · rank 6
Toichiro's son
Beat Ritsu as he was escaping the 7th Division, without the page bothering to show it, and finished the division's own leader, Ishiguro, with one attack after Reigen had beaten him. Inside the Culture Tower he ended Hatori of the Ultimate 5 with a German suplex, then fired three months of stored energy at his father; Serizawa blocked it and Toichiro beat him. In the ???% arc he fought beside the same father, and walked off holding him up.

Leader of Claw's 7th Division
Pressed Mob down with gravity until Reigen dropkicked him, then aimed a black hole at the whole group and held back only to spare his building. Against Reigen holding Mob's power, his black holes burst like soap bubbles and he was slammed into a wall without a scratch. When he would not give up, Sho put him down with a single attack.

What this does not settle
One fight in one work. It is the only result the record gives between these two, 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.
