For my last cycle tour (Tuscany-Corsica-Sardinia), and for warm weather use in general, Trangias are great. They're quiet, easy to use, and I can generally find something useful or pleasant to do while the water gets to a boil. French and Italian supermarkets all carry bottles of denatured alcohol, so finding fuel is easy.
For backpacking/mountaineering trips at high altitudes (2500m +), it's a different story. Mornings and evenings are cold, the water supply is usually freshly melted from a nearby snowfield or glacier, and cooking times can become ridiculously long. Plus, carrying all that fuel in a backpack is a nuisance. At this point I'm happy to put up with the noise and pumping/priming associated with an MSR or other white gas stove. Less fuel to carry, too. Plus, Coleman fuel is still easy to find in the US, and usually cheaper than alcohol.
