I use a JetBoil 1.5 L. pot for its higher efficiency with its "Flux Ring" heat exchanger on the bottom and its neoprene cozy on the sides.

Now that Primus has virtually the same heat exchanger on the bottom of its "ETA" line of pots I'd suggest you try it or a JetBoil pot and see for yourself how much more fuel efficient they are.
