HE pots do give faster boil times too. But it's a bit of a myth that the longer the trip means gas is always more weight efficient. Only in in some few cases. ( E.g. if you need exactly a full canister amount of fuel for the trip). And that's only with a setup no/not much heavier than an alcohol/esbit setup. Once you start using heavier stoves n pans gas isn't really ever any more weight efficient. It's clean,(potentially ) fast, and convenient, easy to use (cookability). ( Good for snow melting?) I use a Jetboil (HE) pot and Soto Windmaster. It's fast and efficient. But mainly only for day walks/Bivi trips and work.
