I never used a "pellet" but I do use an
Akorn (steel ...) kamado and I continue to be impressed with it. But I think that the fundamental process, with kamado, really is that of a "charcoal-fired
convection oven." The food is cooked by recirculating hot air, not direct heat from the fire, and because of this it will cook much faster. (And I don't think that "ceramic" makes any difference.)
To get "smoke," wrap a packet of chips in aluminum foil and place it (with a few fork-punched holes) directly on the fire. But, if you want "sear," you should do that on your stovetop with a cast-iron skillet and coconut oil.
Once you "park it at a temperature," the darned thing will just sit there rock-steady for hours without demanding constant attention from you. And at the end you will
still have charcoal left over. I've never seen anything like it.
