Interesting question, usually both are dangerous snakes, but Indian cobra is more dangerous in terms tht itz venom affects both brain nd heart but kraits venom affects only brain and causes muscle paralysis and death follows in 4-8 hrs in the latter whereas in former signs appear within 15mins - 2hrs of bite but deaths are less in case of Indian cobra bite if anti- venom given on time.
