I've decided on the Alcohol stove for my GHB because of its multi-use. Everclear in the original pint bottle (refilled) - good for the stove, for disinfection, natural tinctures preparation, cleaning optics and electronics contacts, could be suitable for trade or making friends (thus the original bottle), and many other survival uses. Esbit - is nothing even close. The cat can stove is tiny, zero weight, doesn't require a pot stand, could work with many other fuels as well. Just make yourself familiar with its specifics. By the way, it lights nicely with a single spark from your fire steel or spark wheel.

The best cat can design I've found so far: https://www.youtube.com/watch?v=6XQVKLlLQjw
