I would say of the ones I ate raw, 7-Pot narrowly edges Scorpion, which is followed shortly behind by Naga Morich. Scorpion is hands down the worst for the "later effects". I really can't find much good to say about that evil b@$t@rd!
Ive tried both fresh bhuts and scorpions lol they both kicked my ass I found the scorpions more intense..even potawies pickled scorpions left my tummy grumbling
