I partially agree with Ben. With such a small pot, side jets should generally be avoided. I wouldn't say that you should avoid all pressurized systems though...really depends on the concentration of the flame pattern. Minibull makes a pressured jet stove where the jets face inwards, to concentrate the flame into the center of the pot. Check out the link
These work even on Heineken pots. That being said, I like caldera cones...even if they are a bit heavier/bulkier than other setups. Theres just zero fiddling with a caldera setup...quick and fairly efficient ( I only say fairly, because I have more efficient stoves, but they have more moving parts etc).
If you are only doing overnighters, where the weight difference between having to use 1 ounce of alc to boil 2 cups, vs .5 ounces, is negligible, then go with Ben's easy open setup. However, if you are out for a long time, then the difference in half ounces of fuel can add up, in which case you might want to look into a setup that allows you to utilize fuel more efficiently.
