Cookware Recommendations

I'm in the market for some new pots and pans. I currently have Calphalon which I have enjoyed but they are worn out from years and in some of their cases - decades of use and I know that there are a lot of great new options on the market.

If it matters, I do not cook a bunch of fancy things but I do cook for myself every day and I want nice ish. I have heard good things about AllClad but have no personal experience with it and have also looked at some nice cast iron options but want to hear from some of y'all who have good taste and know what you're talking about.

TIA
Are you cooking over natural gas, an electric range, or over a glasstop/IR?
