Temperament: As with many snakes, BCC vary in temperament from quite docile to super agro. In general, I have noticed that they are generally a bit more sensitive and find a higher % of "unpleasant" temperaments that with BCI. One of mine will repeatedly strike at my face when out unless restrained and wags his tail like a dog
Husbandry: Less forgiving, and if you screw up it can be much harder to get them back on track again.
They are similar enough to BCI, if you like them I say go for it
