Raw power is tilted before the argument starts. The interesting part is what survives after that gap is admitted.

In a direct clash, Ryomen Sukuna wins: 3 tiers of separation is a gap that DNA edges alone cannot close. DNA tells a different story: Killua Zoldyck: moral cost they'll pay, Ryomen Sukuna: constant growth arc. These are different character shapes, not different power levels. Killua Zoldyck is the more complex character study despite the power gap: a pattern common in isekai where the weaker character carries more narrative weight.
