I see you found one of the best reviewers out there, in my opinion...good ol' Nigel! I checked the chileman.org database and their description says that they are one and the same. But if you scroll down a bit, there's the Black Congo with an unavailable description. But those look more like the Scotch Bonnet Brown, which I highly recommend.
Yeah he is my favorite reviewer too, I always look for his videos before others. Isn't the Chocolate Scotch Bonnet the same as the Scotch Bonnet Brown too?? LOL
