I like the hatchet because it can also be used as a hammer and even a weapon. You can't do that with the pocket chainsaw.
At some point you have to minimize all of the gizmos you carry. You could have every gimmic available, but you would need a semi to haul it. I would ask myself, "Self, do you already have a tool to accomplish the needed task?"
"Which tool does the most different things?" I would decide between a hatchet and a chain saw and the hatchet would win hands down.
