Well it depends on how you look at it, a bite from a rattlesnake would obviously be alot more serious than that of a kingsnake bite, but if it were like a fight with the two whichever one is bigger would most likely be the one to win, the KINGsnake gets it name from being impervious to venom, therefore the kingsnake could consume the rattlesnake without harm.
Rattlesnake
Both are dangerous, venomous snakes. But the cobra is an elapid, and the rattler is a pit viper.
The king cobra has a venom which is much more toxic than that of a rattlesnake. It is also much larger and can inject a greater amount of toxin.
A cobra and a rattlesnake are both snakes (of course) and they both are poisonous. But they both deliver the poison in different ways and the poison is not they exact same as far as chemistry goes.
