SP,
My personal stove is the Vargo XE. Of course I have all of Vargo's stoves, but I really like the idea that I can drop a fuel tab in there and I'm good. The burn time on the XE is probably a bit longer than the Decagon, about 5 minutes more when running Alcohol. The nice thing about the Decagon, is that there are no moving parts. But thats just about it. My favorite hands down is the XE.
