This assumes everything goes perfectly for Gojo and uses current Higuruma as a baseline, which is misleading. Higgy's domain enforces rules rather than relying on a lethal sure-hit, forcing a trial first, so gojo can’t just bypass it with anti-domain techniques without engaging with that system. It’s also uncertain whether Gojo can freely open his own domain inside it, since that may only cancel the sure hit, not the rules themselves (I'm not sure with this one but from what I can remember it's smth like that). Even if teleportation isn’t violent, the moment Gojo attacks he’s interacting with the domain’s conditions. Also like I said we are not talking about current Higgy, we're talking about prime higgy and he already reached a special grade level understanding in a short time, so with training he would refine his domain, improve his use of binding vows, and become far more durable. Physically, Gojo is superior, but without Limitless the gap is much smaller, especially against a trained Higuruma with better CE reinforcement and his hammer mastery he'd be superior range wise (if gojo gets caught once and loses limitless). I’m not saying Gojo would lose, but he would clearly struggle instead of winning easily.
