Yeah, it's the stuff I usually hear. People go from saying its the ultimate ultralight option, then talk about gathering less wood, more efficient, easier to start a fire, and a faster boil.

The lightest thing to carry is nothing (and burn wood, none of which I carry)
The second is esbit.
The third is alky

None of them are the fastest boiling, most fuel efficient, easiest to start, etc. etc. if those properties were what I most cared about, I'd carry something bigger and heavier that started easily and boiled water faster than the fukushima reactor. As it is I can wait for my dinner, light a fire, and if I can gather one handful of dry twigs I can gather three. I care about something that will do the job, with the least weight possible on my back. Anything else is secondary, at least for me.
