Hard to go wrong, honestly. Jetboil or MSR Reactor for me, just like the simplicity, the Jetboil has seen the most action. I only boil water when backpacking, so it works great. Sturdy, everything fits inside, works as a bowl or a cup, my long handle Ti spoon fits in the neoprene sleeve, piezo lighter. Could I shave a few grams with something else? I don't really care. It would be less than the weight of one round of ammo if I did and I don't want a stove that will fail. Pocket rockets work great too, used one extensively in the past before the heat exchanger type systems came into play.
