Stainless steel pans are amazing when used for the right purpose. They weigh much less than cast iron, don't require any maintenance beside cleaning them, and they are pretty much indestructible. If you burn something badly you can use metal scowering pads or any chemical you damn well like (including sodium hydroxide that will melt flesh) to get the thing clean again. They are tolerant to any cooking temperature you would ever use, ever. You can't overheat one with any appliance a normal kitchen would have. This means you can easily pop one in the oven provided it has a metal handle.

The only issue being they have no non-stick properties to speak of and relatively little thermal mass. This is good in that they don't need long to heat up, but bad in that it's not a consistent temperature and you have to know what you are doing with the power control to get the results you want. This means it's essentially useless for cooking things like steak, and difficult even to cook an omelet without using a lot of butter, ghee, or oil. Things like tomato sauces though? Perfect. The stainless steel could care less about the acidity.
