The larger of the JetBoil pots (1.5 L.) is great even without the JetBoil canister stove. I bought it to use with my canister stoves (Vargo Jet-Ti and MSR Wind Pro) and it IS more efficient than my 1.5 L. Backpacker's Pantry aluminum pot. This is due to the JetBoil pot's neoprene cozy and "Flux Ring" corrugated heat exchanger attatched to the bottom outer edge.
I recommend this especially for winter camping where efficient snow melting is important to save fuel and time.
