I prefer the single coil to the dual coil by basically every metric except hit volume.
Much easier to consistently get great tasting hits
Much easier on the batteries
Much quicker heat up time
All valid points. Just depends on the consistency of the material I find. A crumble works great in the duals as it is easier to "coat" both coils and not loose any. For a sticker concentrate, the single coils work fabulous being able to drop a rice size dab on the center.
