Put me in the Trangia-Esbit crowd. Esbit is ultralightweight and what I use exclusively for backpacking now. The Trangia comes in a close second. If you plan on boiling LARGE amounts of water with a stove, then I would go with one of the gas stoves.
The key to getting good efficiency out of the Trangia and Esbit, is to have a really well-made windscreen. The screen should extend up around your pot with only about a 1/4" gap all the way around. Without a good windscreen, Trangias and Esbit stoves can be pretty miserable.
This is my current esbit stove. The base is the bottom half of a round candy tin, turned over. It has a slight depression in it so when the esbit becomes liquified from heating, it doesn't roll off. The base for the candy tin is made from the lid of another tin can, slightly larger in diameter than the candy tin. I cut the lid off from the side, not from the top, so there are no sharp edges. The pot stand is made from hardware cloth. The windscreen is made from aluminum flashing used on roofs. A paper punch was used on the base to punch holes for ventilation. I have used this setup extensively and it never fails although I have not tried it in winter.
