From what I've seen, the Copper Core has slightly better/more uniform heat distribution (not that the D3 is bad - it's def 105 level) but the bigger difference is supposedly the responsiveness to heat - hotter or cooler - which can make delicate operations a little easier. Oh, and it looks more fancy

This skillet is def not going to be non-stick (I use carbon steel for stuff that needs to be non-stick), I want it for better fond/deglazing/sauces, etc. I haven't actually cooked in stainless for decades, but I think that I have a much better handle on heat management so problems should be minimized (knock on wood).
