I've just replaced my saucepans and I have really appreciated the various topics in these forums that have helped to give me a better idea, but I'm going to throw this out there.... There seems to be a huge number of "me too" All-Clad owners that probably are buying purely because of the name and then swear blindly how good they are - The All-Clad Mafia! - without any appreciation or discussion of any of the short comings.
Being the anal researcher that I am, I tried to do as much homework as I could before making a decision. I went from All-Clad Copper Core to Stainless Steel, very briefly to COP-R and then to "the others". After walking around a number of shops trying and much on-line research, I came to the conclusion that All-Clad really were resting on their laurels and just not that good. Money isn't so much of an object as I was prepared to splash out for a set of the Copper Core All-Clads (if they were worth it). Consensus was that they weren't.
Finally I just couldn't get my head around the fact that the stainless series didn't have pouring lips on them. REALLY? I can understand for larger saucepans but for 1-2 qts, come on....
So I after too much time I have just bought the Calphalon Tri-Ply 1.5qt and 4.5qt - similar construction, similar good looks, PLUS a more ergo designed easier to hold handle PLUS glass lids and cheaper.
To hedge my bets and have a basis for comparison I have also bought the 3qt All-Clad (sans pouring lip) so I hope to have a pretty good idea which way to jump next. I am still in the market for a 2 or 2.5, but will wait to see how these play out and will most likely make the next move into a couple of proper 2.5mm copper Mauviel pieces next time I am in Paris.
My 2 cents worth.
