Best I try to end it quick.
Attack. Omua, that <5x advantage is very beneficial tbh.
Durability: See Attack
Lifting Strength: Omua, M is better than 100.
Stamina: Hunter, he can fight for days which is much better than Omuas extended time, likely lasting many hours for Omua, which is inferior.
Range: Hunter, no doubt, hundreds of meters is much better than fifty meters.
Intelligence: Hunter, due to the fact Omua tends to be arrogant, Hunter is very skilled (even though Omua is somewhat skilled, but slightly inferior), being able to outsmart his opponents.
Experience: Hunter, assuming he is average adult age, that puts him better. Though both are just as skilled, Hunter, thanks to being older, is better.
Abilities: It was a hard choice. As we can see, Omua would be able to try to incapacitate his opponent to suffocate him to death in 1-10 minutes via Mukou Kekkai, and Hunter would be able to put his opponent to sleep and even try to cause these statuses:
...however, Omua is much more durable, and by creating a tornado around him (possibly even blowing the projectiles away!), he can tank the attacks pretty well, as the Hunter would struggle and suffocate to death. Thus, its Omua who takes it, despite Hunters insane arsenal.
Conclusion: It has come to me that the most reliable thing to do is for Omua to buff himself up, protect himself from the bullets, and let his winds strangle Hunter as he helplessly struggles to break free. Despite more advantages, Hunter would struggle to harm Omua anyways, because, 5x. The winner is
Omua Kurogane.
