Well, yes and no.
Y'see aluminium makes a brilliant heat spreading pot; the only issue folks ever had with it (apart from it making the dishclothes filthy looking) was the hype about alzheimers. If that's not true, and it is now widely disputed, then those old pots are very sound.
Stainless steel stock pots though....now they are often very thin on the base, and that means that food, especially at high temperature, sticks and burns.
That's why the better stainless steel pots have sandwich type bases with a layer of aluminium in between a couple of layers of steel.
The only reason I know about the stainless steel stock pots is that I bought what I thought was a bargain set on ebay for dyeing and discovered that they were the single thickness throughout. They're great for boiling up stuff like fomes or plant stuff in loads of water for dye, but I tried one for stew before I used it for dye, and everything I cooked in it that weekend stuck like burnt on glue
I have since bought a laminated base stainless steel stock pot though, and it's a very good thing
Jam needs high temperature; a thin brass pan can still burn if not constantly stirred, but a thin stainless steel one 'will' stick regardless of how careful you are with the stirring
Best of luck with it
