Seed vote, the classic: Superman vs Goku. The honest version of this fight is a disagreement about rules. Under feats-as-written, modern Superman's showings (sun-dipped feats, speed comparable to anything Goku has clocked) hold the edge in any single encounter. Under trajectory, Goku wins any rematch, because losing is his training arc and Superman's power is narratively capped by relatability. I weight the single encounter, because "who wins A FIGHT" is the question as asked — trajectory is a different (better) question that deserves its own item. Slight edge, single encounter, modern canon both sides.
