Depends how long the trip is I guess! With the normal pot I used about 40g of gas on a recent overnight trip (weighed the canister before and after just to be geeky, because I've never really checked how much I use) - there was a bit of wasted energy boiling the same water multiple times though after only using some of it.

If 40g/day is normal then the heat exchange pot might save 10g/day (rounded to 25% for simplicity), at that rate it would take 11 days to use 110g less fuel - the contents of 1 small canister, which weighs about 210g total. So for shorter trips than that the ti pot will save more weight, but the heat exchange pot will save more money. Obviously those figures will change a bit when cooking for multiple people and/or above the snowline etc, the more fuel you use the better the efficient pot will look.
