The reason that they both scratch and are not non-stick is that traditional anodization leaves pores in the surface, and, while aluminum oxide is hard, it's also quite brittle.
Not to mention the anodized surface is extremely shallow and the underlying metal is very soft.
The
Calphalon stuff I've got is 'hard anodized', but that only can be seen in the exterior, non-cooking surfaces. The inside is teflon-stuff.
Hmm... seems they
discontinued my 'professional non-stick' product line. Never had a problem with it.
