Old fridge had constant ice maker problems and door opening issues (removing drawers for cleaning and would run into adjacent cabinet handlers). Ice maker in door leaves more space inside. (Also just spews ice out!) Same interior size as last but seems to hold more. Ice maker side door shelves are a useful depth. Doors also open differently to provide clearance to easily remove drawers and does not interfere with adjacent cabinet handles (delivery guy said something about this design). Water also comes out at a nice rate (last was a very strong stream that if you were not careful...)
