I like the manga better than the anime. What a surprise. Just because they get to give the subject the depth is deserves. You get more of Kaneki's tortured emotions, as well as the various ghouls. It's not like Tokka enjoys eating humans. She'd like to fit in with her friends. It's a dark subject. It's easy to see why it would be hard to handle, like Attack on Titan. People eating is squicky.

Though, if you do enjoy that sort of body horror, I recommend Parasyte: The Maxim. It's about parasites that invade human bodies and take over their heads and subsequently go out and slice people up and eat them. Izumi Shinichi had one try to do that, but he tourniqueted his arm with an ipod cord and managed to contain it to his right hand/arm. It goes on to deal with the consequences of having an alien parasite in his body and eventually confronting other parasites in the world. Like Tokyo Ghoul, there's body horror, gore, eating people, teenage angst. I've really been enjoying it.
