Contours: Cartographic vs. Engineering

Esri documentation indicates Contours generated from Spatial Analyst are "engineering-quality". Is this really true? I'm comparing with a Global Mapper output that indicates its only "cartographic-quality". But as you can see in the attachment, they "appear" very similar. The were both produced from a very accurate LiDAR-based DEM. For the record, the red lines are ArcGIS; the brown lines are Global Mapper. The horizontal spatial offset is noticeable. For reference, this is about 1 to 2 feet. ...Any thoughts on this distinction? Thanks.
