EJ, I prefer Esbit or the similar MPI tabs to Coghlan's for a couple of reasons. For one, they're in a blister pack and so are protected from water and humidity. Also, they smell like fish, so the blister pack keeps the odor out of the rest of my gear; any opened blisters go into a zip-lock for the same reason. When I do have to resort to Coghlan's I pack the small, round tabs in an empty Nuun's electrolyte tab container to protect from moisture and control odor. It holds about seven tabs.
On average I boil about 2-3 cups of water at a time, which consumes < two Coghlan's or one Esbit tab. The set-up I prefer is a BPL wing stove, Ti wind screen, and a wide diameter pot like the MSR Titan or Anti-Gravity Gear's .9 L alu pot. A wide pot is preferable to a narrow one for max effiency from these little tabs. Happy trails!
