depends on which set. the zwilling sol II or truclad (slightly thicker, better handles version of Sol) would be equivalent in terms of construction but those are made in china while all-clad are made in USA. if you go up to belgium made Aurora or Sensation line then those are 5 ply and better than D5 IMO. anything below like the joy set or bonded base then all-clads are better imo.
