Differences in manufacture:
Kufala's were released in a Tri Fold Cardboard sleeve that had 2 logo's printed on the sleeve, one on the inside for Backspacer and one on the outside for Pearl Jam. Also the CDr also had a noticable blue dye on the recording surface, while the printed side of the CDr is glossy white.
Nugs.net are also released in a Tri Fold Cardboard sleeve, but it is absent of the Backspacer or the Pearl Jam Logo's above. The CDr's also have a matte finish on the printed surface while the recording side is more silver than above as well. Another difference is the size of the sticker on the front of the release is larger and covers more of the front of the sleeve.
