Any firestarting material is going to work as long as you know how to use it and practice using the materials. Ultimately, you should learn and perfect as many ways you can find on how to start a fire. The knowledge of the various ways, the materials needed, and the skill to use them is much more important than which Mg firestarter is the best. Lets face it, you could have a propane blow torch to start a fire, but if you don't recognize it's value or the knowledge on how to use it, it might as well be a rock.

Test this. Take your wife out back, show her a disassembled hand torch (one with the knob and no electric starter) and a lighter and see if she can tell you what it is and figure out how to use it. I suspect 1 in 2 can't do it.
