A serious competitor to the Simmerlite, because of its fuel efficiency and cleaner burning (better for tents, vestibules, snow caves, etc) for melting snow in the winter. There is still some question about its ability to perform in seriously cold (subzero) conditions, but the Simmerlite suffers here as well (use an XGK with its larger generator tube for subzero conditions). Also, the Xtreme is still too heavy, but there are options to modify it.
Make this a sub-8-oz stove and it gets a strong 5.
