All-Clad's patent for triple ply pans expired, so now you'll see a ton of brands able to do it. I bought a $215 Cuisinart Multiclad Pro set 4 years ago and it's been good and held up well. Biggest pan was 10 inch, so I bought a 12inch All-Clad that is my work horse and high-temp seering or stir fry pan. Even the cheaper Tramontina get good reviews (and more importantly good heat distribution in testing) because the All-Clad patent/tech was just that good it can now be duplicated with great results for cheap. All-Clad is superior quality still, but imo not worth the cost if you're cheap like I am, unless you're trying to impress or really beating up pans in a professional setting (and even still I'd honestly almost prefer 3 or 4 cheaper pans to be more disposable of sorts).
Also added a mid-size Cuisinart pot smaller than the larger stockpot that has drain holes on top. I wanted the size, but the gimmick of drain holes on top has been great, too.
For cast iron, I have a smoothed/machined Griswold 10inch that is amazing for everything from crisping tortillas to seering. My newer Lodge cast iron is annoying to work with. The factory seasoning sucks. It's rough, which some people claim doesn't effect the non-stick nature, but shit sticks to my rough Lodge cast irons no matter what in a way that never did with smoothed ones I learned to cook on as a kid (that I wish I still had). And the rough surface makes it obnoxiously loud to work with metal utensils in it. Some very nice/expensive brands machining the surface smooth or can do it oneself, or look to find an antique pan from Griswold or Wagner that will be far superior (and probably have all the lead leeched out by now? hah).
That said, cast iron baking sheets are amazing if treated like a baking stone for baking and expecting some cleanup for roasting. Have smaller ones we do bacon or biscuits on in the toaster oven. Large round pizza pan that works best treated as a baking stone. Even have cast iron bread loaf pans that are great for a better crust and faster cooking. And they'll all go on the stovetop to use as griddles, too. Otherwise just basic Nordic-ware is still king for baking.
Nonstick for anything in the kitchen is an abomination. Releasing toxins, teaching people bad/lazy habits, and not lasting nearly long enough to bother with them. Whether it's chemical coating style or marketing about some new and improved surface, it's just not worth bothering if you're at all serious about cooking/baking.
