[Raises hand] Have done some pretty detailed comparisons, maybe most notably a Ti pot versus an Al pot with heat-exchanger, and found no meaningful difference in fuel consumption or boil times. (Although the second measure is a canard with any stove having a valve--alcohol stoves are another matter entirely.) I use a remote thermometer to determine when the water hits 212, rather than declare when it's boiling, and make sure the starting temp is consistent.

For anyone concerned about maximizing fuel efficiency, prefer a lower, wider pot, snug lid, efficient windscreen and a stove with ideal pot support height and wide flame.
