I don't know shit about lighters, other than mine are always Bics for some reason because of the funky designs on some of 'em.
Counterintuitive, but torch lighters use less fuel. There are two holes in the gas line before the flame, which suck in oxygen because of bernouli's principle, and they are mixed properly so it burns hotter and nicer.
