^^ Eto and Tatara demonstrated control over their psyches before (and, in Tatara's case, while/after) allowing themselves to let go and fight fully in berserker mode. In Eto's case, she was enjoying her fight with Kaneki but still had the sanity left to leave behind her kakuja's shell for him to eat, and Tatara was embroiled in his hatred but was able to formulate battle strategies on the spot, in addition to being surprised (in a sane "hey dude what are you doing" way, not a "BWUGWUH" way) when Takizawa turned on him.

^ That's how I've been viewing it. That kakuja transformation increases all of the most brutal and vicious aspect of the ghoul using it (like Super Saiyan originally was but with more gore and crying), and so it requires enormous willpower to be able to use it without losing one's mind.

Besides, if there's ONE thing we can definitely say Kaneki doesn't have, it's inner peace. He's settled his fights with a couple of his demons (mainly the "I'd like to die now kthnx" one), but now he has an entire world resting on his shoulders in addition to the grief that drove him to that point in the first place - and we know he's still bearing the burden of grief due to his little flashback of lost allies and his fear of sending Touka out into the field even before he knocked her up. Even just the way he interacted with Akira was enough to make it obvious how much it still affects him.
