I bought the Evernew stove for what seems to be the same reasons you did - I wanted something light and virtually indestructible. I was disappointed when I used it in the field though. It didn't boil water as efficiently as the 12-10 stove that came with my Caldera cones (I have a couple).
With my Caldera cone and Evernew 640 ml Tall Pot the 12-10 stove will bring a pint to a boil with 15 ml of denatured alcohol. I found it took 25 ml with the Evernew stove to consistently reach a boil.
I haven't measured the time factor in reaching a boil - I'm not using alcohol because it's quick - so that may be a difference, but time doesn't weigh anything in my pack so I focus on how much fuel I need to carry for x number of pints of hot water.
My tests were NOT scientific - perhaps I had water temperatures that differed greatly or something like that, but the Evernew simply didn't perform as well as the 12-10.
