Zelph is taking the time to state the obvious, since it's an issue dear to his heart.
We like to differentiate stove performance based on a few finite categories; canister vs. alcohol vs. white fuel, whatever. It's not even close to that simple.
Denatured alcohol (in the U.S.) is about as vague a "definition" as exists.
We don't assume that our propane grill will run on a natural gas supply(vague), we don't try to hook it up to an acetylene tank either usually, or some combination of various gases and call it good.
Ranting as usual, but the point is, in most applications, stove burner performance is *highly* tuned based on the requirements of the fuel, and it's optimal combustion concerns given the application, and if we want optimal performance from "alcohol" we need to consider that.
However, in that vein, I'll say that it's up to the alcohol stove makers to clarify what fuels and conditions are ideal. Cannister stove makers do that, by simply limiting their products to a singular platform.
Personally, I like to design my alky stoves around 190 Everclear, since it's about as clean as it comes, and is on par with a fake cyanide tooth in making you forget (and feel like sh$t in the morning). I tried sunnyside based on the paper, a couple years ago, and wasn't impressed.
