Titanium, aluminum, or stainless steel for a camping kettle?

Titanium is the lightest and most corrosion-resistant but conducts heat poorly (hot spots) and costs the most. Hard-anodized aluminum conducts heat faster than titanium and boils quickly for the weight, but it scratches and dents more easily. Stainless steel is the heaviest but the toughest, handles open flame well, and is the typical pick for car campers and bushcrafters who don't count grams.
