I like to hike fairly light but I still make room for a flash boiler as a luxury despite weight. This thing takes the pain away from cooking. I’m always impressed by how quick and efficient it is.
I own a Chinese manufactured petrol stove which works ok. It’s a pain to light however. Never used an alcohol stove myself but I have hiked with a friend using one and that seemed painfully slow. Can stoves seem like a novelty to me. A nicer burner is not particularly expensive nor is it that heavy.
