The weak link is the paint on the line. Once It fails at any point it will spread. In your case the nut likely cut through the paint during installation allowing the nut to weld to the line.
When using machines to fabricate, steel lines have the advantage of rigidity they stay perfect from fabrication to installation so there are definitely benefits.
Nicop Is 10x easier for DIY so the advantages vaporize quickly.
