I am sure both of these cookers are great and I can only talk about the Backwoods as I have used them for years.
These great cookers are designed to where you can cook direct, raised grid direct, indirect, with or without water for the higher temps, and grilling right over the coals and are very close to air tight which makes it possible to operate at many different temperatures. They will just flat do it all!
From smoking cheese at less than 80 degrees, to smoking something like jerky or sausage at around 140-180 degrees, to smoking your normal low and slow meats at around 225-250 degrees, the cooker does fine job on the low end of the cooking temperature scale.
It also does a fine job with the medium high temperatures as well. Running around 300-375 degrees opens the door for many more cooks including casseroles, chicken, high temp butts and brisket, bread baking, turkey and turkey breasts, beef roasts, soups and stews, etc..
The temps above this at maybe 375-450 are great for pizza and many of the higher temp baking breads.
With the cooker set up direct for grilling, you can do wonderful steaks and chops, high temp veggies, fish, and other grilling treats at the tip of a lump fire flame and I would guess that the temps would be around 1000-1200 degrees.
What is not to like??
Smoking cheese in the Backwoods Party at 80 degrees.
Ten grids full of jerky smoking at about 160 degrees in a Backwoods Party.
This complete cook was done in the cooker. It is prime rib, baked potato, green beans seasoned with country ham, yeast rolls, pineapple upside down cake. One great meal.
Here is another whole meal that was done on the cooker. This is t-bone steak grilled direct, my slab potatoes and onions, smoked green beans, Texas toast and this started from a loaf of Amish bread that was done on the cooker during this cook and then grilled up with some garlic stuff, and my Swedish nut cake.
This is a whole pig in a Backwoods Competitor which is a cooker about the size of the standard Stumps.
This is 4 pan pizzas in a Backwoods Party and these cookers will do a great job with both hearth and pan baking. Also great for most desserts and party breads.
You can see the above cooks plus many more on my blog. Just go to the table of contents and punch up Backwoods.
