So, I've been wanting to share my opinion on this based on peppers I've grown and tried. Now this is in no way exhaustive, or even scientific. For example, for some reason to me Jalapenos are hotter than serranos, so take this next list with a grain of salt.
From "mildest" to wildest this is my opinion and please share yours and your opinions.
7. Bhut Jolokia
6. Trinidad Scorpion (Red)
5. Moruga Scorpion
4. Chocolate Moruga Scorpion
3. Chocolate Trinidad Scorpion
2. Carolina Reaper
1. 7 pot Brainstrain
Just my opinion and please keep in mind that I've only tried these peppers I haven't tried the newer varieties or all of the 7 pot varieties only these.
