What is stronger a cobra or rattlesnake?

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.
