Another thing to ponder at perhaps is the fuel to water boil factor, even if your not concerned with time. Like Bitterroot Bulls mentions it's good to add all the weights, fuel, cup and stove to the equation.
MSR pocket rocket, water boiled per 100 g fuel 6.6 liters
Jetboil, water boiled per 100 g fuel 10.0 liters
One could perhaps always go even lighter and less costs if your not concerned with time and build a open fire and have a Snow Peak 4.8 ounce titanium cup to boil water. There are lots of options but I like the Jetboil Sol TI weight to fuel boil ratio myself and ease of use.
