I travel with either a Simmerlite or a DragonFly as my primary stove.  My back-up stove is a Peak 1 ... generally the "all-in-one" rather than the component equivalent.  The Coleman stoves are generally superior to other stoves for simmering.  They just tend to be a bit more bulky.

As I recall, the Snow Peak Giga has a roarer-type burner like the DragonFly ... at least that's the configuration of my white-gas version.  Good burner, but typically a bit noisy.
