2 different cookers, do you want to use water? I think the backwoods gives a more pronounced smoke, the gravity feed, can go on forever.
With the backwoods, you can set your burn up and not add wood or coals until your done, with the gravity i have to add wood every 1-2 hours for the first part of the cook to get the smoke i like.
I also think the backwoods puts color on faster than my stumps, good or bad, it does, it also cooks a bit faster.
both quality smokers but different.
