The comparison is strongest when power scale, story role, and DNA dimensions are kept separate until the final read.

Seiya Ryūgūin has a slight tier edge, but one tier rarely decides outcomes. DNA becomes the real tiebreaker. DNA tells a different story: Killua Zoldyck: self-determination and identity, Seiya Ryūgūin: constant growth arc. These are different character shapes, not different power levels.
