^ it was told by Itori at the way back in tg due to their hybrid nature.

Though nothing was further explained but biologically hybrids has higher heterozygosity which they can express in their phenotypic nature. We have such ambiguous background of ghoul biology but it is known that generally in heterozygosity, the dominant alleles are phenotypically expressed and with higher heterozygosity, an hybrid is likely to express both parents traits; you can say something like being the best of the both worlds if it is the positive heterosis. Genetic is such a large field to be discussed here and since real science and biology might not be not appropriately applied into a manga with little background of their fictional species so I dont know how this might be helpful. Also, adding to the fact that I am not a biologist( well, I'm in medical field so I got myself some basic knowledge on genetic, but certainly it's not enough) this some of the information might contradict or too general for hybridization stuff.

tldr: Itori had this matter explained from the early tg chapter that naturally oegs are superior to a normal ghoul and I just stick to the manga information for the fact.
