Spoiler:

She functions the same way as Yogiri do. Because they are the absolute finality, whatever they say and do supercedes everything else when a World Conflict occurs and the reality well adjust itself to it accordingly. But because they are both the finality, they can't supercede one another.

OK, so, roughly equal then. Still no one you can seriously call stronger, and again I feel like both are kind of outside terms like "OP". For me, OP implies an actual power, as in something that you do and expend effort to carry out. Both of these are physical forms of absolutes. They don't do something that kills people, they just want someone dead and that someone is dead on any and every level. Rather than "over-powered", a better term might be "meta-powered". There is no "stronger" on this level, since what they will happens no matter what.
