The "trick" that OnGuard used to block the use of power tools was a padlock with a shackle that is enclosed. That forced the testers to attack the chain instead of the padlock. A cheaper OnGuard/Magnum chain that used a standard padlock with an "unshielded" shackle was easier to cut.

Some stores are still stock 2004 model OnGuard chains. The high rated OnGuard chains had 12mm links and the padlock with the covered shackle. In the past, OnGuard has sold several models with the 12mm links, with the primary difference being the length of the chain.

The article did not specify the model of the Abus padlock that was used. The Abus padlock looks like an ordinary padlock, but used a hardened steel that resisted cutting. The padlock has the "Granit" name on its front and resembles a photo of the Abus model 37/55 on the Abus website.

The Kryptonite chains used a high quality steel that resisted cutting. However, surprisingly, the Fahgettaboudit padlock was cut with a few minutes of effort.

In contrast, "Bicycling" Magazine did a test of the Fahgettaboudit in which their testers were unable to open the Fahgettaboudit using standard breaking techniques. "Cycling Plus" used power cutting tools in their tests...not a common technique for crooks. The Fahgettaboudit is plenty strong against the types of tools that are most often used.
