We have established that Teresa is the most powerful Claymore and that she could probably face the Abyssals head-on with ease.

But the 4 who went to hunt her, while we knew they were strong in that generation, I think they would be in any generation. Irene mentions that both she and Sophia and Noel surpassed Teresa in some stat (being speed, strength, and agility, respectively). We don't really know if that's actually true, although I consider that it is and that despite being slower or weaker than some of them, Teresa's yoki perception and her high overall abilities gave her the advantage. Although of course, this is before activating the silver eyes.

This is without even mentioning Priscilla, who was one of the strongest number 2s despite being a novice, and who it was said could defeat Teresa with a little more time.

In any case, the mere fact of even getting close to Teresa makes them top-tier among warriors of all generations for me. What do you think?

Rosemary was number 1 after finishing off Hysteria, at least until Teresa took the position from her. This is told in a special chapter about Teresa, in which she faces her in her awakened form.

I know she was number 2, but considering that at least for a time she was number 1, she could technically be considered an Abyssal. Of course, we could say that she only took the position provisionally and quickly lost it, implying that despite being number 1 she wouldn't have the typical level of one.
