Actually, since the rating is based on a ghoul's "threat level" rather than just "strength" Kaneki would easily be SSS. Even if he was still just SS+ in terms of strength, his knowledge of the CCG and the intel available to him as an Associate Special Class means he would still pose a massive danger to them if he were to oppose them. I mean, if he leaked all the stuff he knew about the CCG to Aogiri, or any other ghoul organisation, serious damge can be done form that alone.
