The useful question is not who is stronger. It is how the same story-world makes two different identities legible.

Different power types make direct strength comparison misleading. What matters here is the character identity gap: what each existence does to the world, not who hits harder. DNA tells a different story: Echidna: raw destructive ceiling, Rem: constant growth arc. These are different character shapes, not different power levels.
