My recent purchase of the Brunton lander, named for the look of the mars lander(whatever) looks aside its a great stove, a bit heavier than the bantam at 14oz but seemed to simmer well in my opinion which is very limited, I have only carried white gas stoves starting with a coleman then the brunton olympus now the the lander.
I like liquid fuel, as it can be used to start fire when wood is wet as well as clean off sap.
I'm not quite the tester you are and base most of my opinions on long term performance, and ease of operation. Anything boiling a liter under 5 min is good enough for me but I will say that brunton makes there stoves to last.
