There is no ‘one best’. I use stainless-clad aluminum, general non-stick, cast iron, and enameled cast iron dependent on what is being cooked and how I’m cooking it. I’m a cheap bastard for the most part, and look for the best price/performance ratio for my cookware. I find that restaurant supply stores are the best option for this. I’m of the opinion that my pots and pans don’t have to necessarily look good, but they must work well. I personally haven’t worked much with anodized aluminum, but I’ve heard good things.
What I do look for:
-
riveted metal handles. I like to move from stovetop to oven. Some of the non-metal handles claim to be oven-safe to a certain temperature. None of the metal handles should have a problem at any temperature.
-
tight fitting lids. Bonus points for lids that can be used for more than one pot. Glass lids - not so much. Tried them and came to the conclusion that seeing inside the pot (when you could see through steam and condensation) didn’t add anything to the cook.
-
heft. Heavier pans tend to hold heat better when you add cold food to them. When you are cooking frozen french fries in an enameled cast iron dutch oven, the oil temperature will rebound to a good frying temp much more quickly than in a flimsy dollar-store dutch oven.
