What each of them is ranked on
The killer05––·
Series Inovel
SCP Foundation · SCP-682 · stated
Observed moving and speaking with its body 87% destroyed or rotted, and adapts to prior damage.
SCP Foundation · SCP-682 termination logs · shown
Repeated documented attempts at destruction, none permanently successful.
SCP Foundation · Experiment Log T-98816-OC108-682 · shown
Cross-tested against other anomalies; devoured two SCP-939 instances, and survived a 27-hour exposure to SCP-096 having lost roughly 85% of its mass.
The Foundation has tried to destroy it repeatedly and written down every attempt, which makes it the best-evidenced entry on this page: the record is a series of documented failures by an organisation with unusual resources. It has been seen moving and speaking with its body 87 per cent destroyed or rotted, and it adapts to whatever nearly worked last time. Durability is not capability, though: nothing has removed it, and it has not remade anything either.

Series Inovel
SCP Foundation · SCP-939 · stated
Lure prey by imitating human speech in the voices of prior victims, including victims they have never heard speak.
SCP Foundation · Experiment Log T-98816-OC108-682 · shown
Two instances were devoured by SCP-682 after refusing to attack it.
Pack predators, red and translucent, that hunt by imitating human speech in the voices of prior victims — and the file records specimens doing it for victims they were never present to hear. They are quick, climb well, and are effective enough in a corridor that the containment procedures read like a hostage protocol. The ranking is set by the one time they were tested against something above them: both instances refused to attack, went on repeating their borrowed call, and were devoured. A predator whose whole method is the ambush has nothing left when the thing it meets is not listening.
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.
