I always liked the CorningWare "Visions" glass cookware because I liked being able to see inside. As stated before, I love a glass lid.
I thought being an "adult" was getting the "best" set of MATCHING cookware because I thought that was how you were "supposed" to do it. But when shopping for sets for myself, it never felt prudent because there was either something that was missing or a piece I didn't like and wouldn't use.
Now I definitely feel like sets are useless if it's filled with pieces you won't use anyway. The only skillets I use are cast iron, my favorite saucepan is one I got at TJ Maxx a couple years ago, and my casseroles are still my "Visions". And nothing is Teflon which I regret once being beholden to (Except for the brand of electric pressure cooker I have which was a mistake).
I do covet more luxury cookware (like the Le Creuset); but, frankly, it wouldn't help my lack of cooking skills anyway.
