The weight difference of the stoves/pot is constant for the trip, while the fuel difference only reaches its maximum near the end of the trip, assuming you take the same amount of fuel for either system. (This favors Ti pots)
Another way to look at this is how many canisters you are going to take. Using your figures the ETA Power ,229 g fuel , / 7.92 is 28 liters, while the average upright and remote would get between 17 to 19 liters. So if you need to take an extra canister (12 oz) it becomes closer weight wise , but you also save some cost on fuel and waste of canisters? Partial canisters? Margin for error?
EDIT: In this case as the stove with the Ti pot burns more fuel the difference of the extra fuel weight should go down, except for the extra canister weight itself remains the same.
Winter time more fuel used to melt snow for drinking water. Snow is hard to melt?
