Lullabelle is 4-B+, she's the strongest 4-B as far as I know, being several hundred billion times stronger than baseline Solar System level - which warrants Solar System level+

Said superiority carries over to her High 3-A and Low 2-C keys in multiple ways (and her yet-to-be-added Tier 1 key), so Attack Potency wise, she's likely the strongest High 3-A and Low 2-C from what I've been told.
