Personally, while I see the deterrent nature of OC, which I think is much safer in numbers, I also know that the bad guy is not going to OC, and he is usually going to try to identify his biggest threat before he acts. The whole idea of CC is that you have the upper hand in secrecy if you happen to be present during a bad situation. If you OC, especially without other people to watch your back, you stand a strong chance of being the first person shot in the back of the head...
The OP has asked that OC vs. CC be discussed elsewhere.
