Smoked powder is all I know. Can't imagine anything better.

This is a really good question and will be interesting to see other opinions.

For me I think it depends on the pepper and the application. I dehydrate and smoke. All my cayenne's are dehydrated, smoked just don't seem right. All my Fresno's are smoked, they make a really good powder. Ghosts and scorpions are done both ways. I am experimenting with other varieties.

Some peppers seem to have different flavor profiles. I don't think I will smoke Aji Limons and I am not sure I really like my orange habs smoked.I smoked some Aleppo the other day but haven't tried them yet. Aji Rojo is next on the smoking list.

it really depends on the application. not everything tastes good with a smoky flavor (most things, but not everything) whereas everything tastes better spicy.
