mmmm ... I think there are many variables to compare , like the ribbed /vs/ straight walls, the diameter of the pot ..etc. In the volcano stove , the cooking pot has a larger ratio of surface area to volume, but in the caldera, you have a larger area at the bottom of the pot, where most of the heat is.

I haven't compared the Swiss Ranger Volcano set up with the Caldera Cone.

You can't fit an alcohol stove in it easily, and, frankly, it just looks kludgey. I know there are those who like it, but I've never been that attracted to the Swiss Ranger set up.
