Cooking has been a hobby of mine for decades now. I have gone through a lot of phases in cooking, especially early on.

I have used cast iron, carbon steel, stainless steel, and a dubious flirtation with all aluminum.

16 years on now and this is what I reach for 100% of the time:

Skillet/sautee: cladded stainless. Both standard side and high sided.

Dutch Oven: Enameled cast iron.

Pots Pans: Cladded stainless steel. For smaller 1qt to 2qt I like All Clads D5 for its heat retention. Larger than that I like the D3 for its lighter weight

Grill Pan: cast iron. Hate the excessive weight though

Non-stick: Ceramic coated aluminum. What ever Americas Test Kitchen recommends that year. I consider these disposable items. I stopped using TEFLON a long time ago.

I used cast iron skillets for several years. I found them to be finicky. Heat retention was stupidly high and that's not always a good thing. Excessively heavy and god forbid you attempt any sort of tomato based sauce or anything acidic for that matter. Circumstances forced me to use stainless steel and I just found it matches my needs in a kitchen much better than cast iron. It gets used, it gets cleaned and I put it away. No having to have the vaginal juices of a thousand virgins on hand to make sure it doesn't destroy the next egg I try to cook.

I consider cast iron skillets like safety razors. They had their day, but continue on because of a dedicated set of die hard users. Nothing wrong with that, just not my thing.

The above goes for carbon steel as well, although it usually isn't nearly as heavy.
