I have the D5’s, and you should know that they are quite heavy, but not as heavy as cast iron. I’ve seen many comments that the D3 are much lighter, if that’s helpful.

I’ve only had sticking issues when I first started cooking with them, until I got a feel for my temps, as I was using cast iron exclusively before trying stainless steel. I much prefer the AllClad now, and only use the stovetop cast iron to sear beef.

This is also why I have D5. I don’t pamper them at all, I’m kinda wild in the kitchen, but the one thing I do take care in is scrubbing and drying them before they’ve even cooled off. Still look brand new!

I bought D5, but like another user mentioned, I chose them over the D3 (and even the copper) only because I preferred the look, and it wasn’t a financial hardship for me to do so. I would have been totally happy with D3 if I liked the shiny finish or if that was better for my budget.
And the D5 are quite heavy, as others have warned. I have to use both hands to lift unless they are empty, and I ladle instead of pour a lot of the time, now.
