The idea of C being a public relations agency resonates for me. I prefer the C/U dichotomy to the superego/ego dichotomy because whereas in both cases it is U or the ego that represents my real self, the first theory has U in agent-control and trying to mollify C, the second theory has the superego in agent-control and embarrassed by the ego. I feel like the first theory more closely fits what I experience, especially during indecision conflicts. Without any guilt, I'll ask, what is the minimum I need to do to feel external-world/socially comfortable here? Because my main goal is be true to my 'self'. Also, morality doesn't consistently break evenly on one side or the other in these conflicts.

So I disagree with the idea that everything altruistic and good about a person goes in C, and that U is an ugly, selfish animal. I only agree that U is socially unacceptable. For one thing, empathy is a basic, natural emotion and society teaches us to repress its natural expression as much as it teaches us to express it in fake ways. C does feel like a liar (I think this is because U doesn't understand and isn't convinced by propositional arguments), but C needn't actually be lying, or representing a better or worse aspect of yourself. Its just useful. (Here on Less Wrong, I feel like we are all 'U's trying to double-check what C is doing and make it more correct.)

I agree with Tim Tyler, that consciousness containing the things you need to be able to reflect on in order to function properly would be more basic way of delineating the conscious mind. Combining this with the idea of C as the public relations agent, this turns into: C is in charge of everything U doesn't do naturally on its own, in order to relate to and succeed in the outside world. If U can't relate to people starving on other continents, C uses logical reasoning to try to care and develop an identity as someone who would care. If U wants to sit down next to the beggar on the street and help him gather resources to survive and feel good, C has the reasons why that isn't practical or good for U in the long run. Indeed, C is our agent, especially our public relations agent.
