I've only ever used my cast iron DO so I can't spout off about "this is superior to that" and vice versa. It would seem a bargain but the size doesn't seem to be one I would be able to use. A 16" DO is very large and the volume might be too much unless you were cooking for the whole camp and not just your family. Not sure about doing breads in an aluminum 16", maybe?
There is an internet forum about DOs and Dutch Oven cooking. They are every bit the enthusiastic, passionate, gear geeky, opinionated, self righteous, know-it-alls that we are on ExPo but their snobbery is dedicated to Dutch Oven Cooking. Spend a couple hours on their forum and you’ll learn all you can absorb about DO and probably swipe several great recipes.
PS: Be careful when using your internet browser to search the term “Dutch Oven”, probably best to include the word “cooking”
