I've got that vargo stove. Sometimes it works ok, sometimes I end up swearing at it.
It's really all about wood prep. If you just grab a bunch of sticks it works ok, or does not work. Take some time to split some good sized limbs to have good dry wood, and it works pretty well.
I'm adding a few esbits to mine in the future.
I end up not carrying it very much.
Good option if your region allows it. You've got to be patient, 15+ mins of wood prep and burning to get a boil was the norm for me. Light as heck. My whole setup, pot and stove ran 8oz.
Not sure I would relyie on it on an extended trip yet either.
