Hands down All Clad for me. They are expensive but you get what you pay for.
I have been using the All Clad Stainless for about 6 yrs and they still look brand new. I love the way they cook as well. I paid about $120 for a small pot and then i paid about $600 for a set of 7 pots, etc. I LOVE them and they are worth every penny. You can also put them in the oven but I have not done that.
I also used my well seasoned cast iron that is about 20 yrs old as well. I love cast iron as well.
I have a white Kitchen Aid flat glass cooktop. It is 3 yrs old and still looks new because I clean it everytime I use it and I take good care of it.
Invest in good quality All Clad (not the cheap knock-offs) and you'll be happy.
There is no wobbly with the best All-Clad or cast iron.
