Naruto's versatile jutsu arsenal and shadow clones overwhelm Sonic's pure speed approach.
Sonic is faster in a straight line, but Naruto's combat toolkit is dramatically more diverse. Shadow clones create numerical superiority, truth-seeking orbs erase matter on contact, and sage sensing can track even the fastest opponents.
Super Sonic's invulnerability is the main argument in the hedgehog's favor, but it's time-limited. Naruto in Six Paths mode can sustain combat almost indefinitely with his massive chakra reserves. If Naruto can outlast Super Sonic's ring supply, the fight becomes heavily one-sided.
Naruto's tailed beast bombs provide area-of-effect attacks that are harder to dodge than targeted strikes. Even at Sonic's speed, running through an explosion the size of a mountain is problematic.
Shadow clones, truth-seeking orbs, massive AOE attacks, and near-limitless chakra reserves. Naruto's versatility far exceeds Sonic's 'run fast and spin' approach. Sage sensing tracks fast opponents.
Sonic's speed is his primary advantage and it's substantial. Super Sonic adds invulnerability. Chaos Control could theoretically manipulate time. But Sonic's attack options are limited compared to Naruto's jutsu arsenal.
Naruto wins through superior versatility and sustained combat ability. Sonic's speed keeps him competitive, but Naruto's diverse toolkit provides answers for speed-based opponents.
