Which of these two do you think would win a Death Battle? Explain Why if Needed

I think Greedling would win. Despite that Kiba's attack's are multiple and can knock any of his opponents out, Greedling is a Homunculus who can regenerate if he is hurt. Not to mention that his Ultimate Shield can block his opponents attack without a problem so he can block Kiba's Fang Over Fang with just his hands. Plus Kiba can get arrogant at times when he fights, same with Greedling but at least he knows not to underestimate his opponent a second time.
