I would say king cobra, since its neurotoxic, ie can give you cardiac arrest, coma and death, and the death adder is mainly haemotoxic. ie blood poisoning, also able to be life threatening, but more likely to lead to local damage, such as disabling a finger, hand or arm. However, which is the more dangerous is maybe more relevant, since the king cobra usually is not aggressive, whereas the death adder is more so. Hence one would be more likely bitten by the death adder.
