Simple.

It is about the maturation state of the kakuhou.

Urie got a already matured one implanted which just became part of him.

Kurona started with a "juvenile" kakuhou from rize and canniballized for years in order to make it reach "matured" stage and grant her "true ghoul" status.

Takizawa and Amon got theirs from Yoshimura, which posses the genetic code which appears to be hampering the maturation process of the kakuhou naturally, allowing for creation of natural OEG such as Eto and also only grants Takizawa and Amon one kakugan each due to the genetics involved.

Kaneki has been on rc-suppresants for years, effectively stunning the growth of his kakuhou and kept it in a "juvenile" state in contrast to Kurona, letting him have only one kakugan as well.

It is all about gneetics and maturation process of the kakuhou involved, that´s all.
