The particular model of alcohol stove I have is a SS Simon Alcohol Stove originally marketed by Safesport. Performance specifications are stated as:
Boils a pint of water in less than 4.5 minutes
Boils 2.5 liters of water per 4oz of fuel
Burning time is approximately 22 minutes at maximum fuel capacity

That's been more than adequate for my needs for most bicycle touring and reports are the Trangia and a few other models are even better. I have owned an Optimus 99 white gas burner that was used in four different countries over a 20 year period as well as several butane stoves (which I still have). This one may not be everyone's preference, but alcohol stoves can be extremely functional and I'm still very comfortable with this one in spite of the improved stoves currently available. I have a second that was ocassionally carried as a back-up and never needed it.

This shows it against a Trangia and discusses some of the further advantages of the Trangia. It also demonstrates the complications caused by lack of experience. Its actually quite simple to calculate the anticipated burn time required and measure out fuel accordingly so there is no 'left-over fuel' issue.
