Weapon or Skills? which one have higher hunting success rate?

I do some hunting so far on grade 3 monster up to grade 8 monsters, use various of weapon but i think there’s not many difference between them, its just they’re faster or slower, so the most important things on hunting is your weapon or your skills? because i ever try to kill grade 4 with just Kulu Ya Ku grade 2 weapon and its do the job done, well its 2 second left
