Bostik's evaluation of the above products:

The ultimate quality and performance of hardwood flooring is dependent upon thousands of factors too complicated for this correspondence. However, the samples submitted of the above referenced flooring materials were tested for adhesion using a representative sample of Bostik's moisture cure urethane adhesives. Test results showed excellent bonding characteristics that are consistent with other similar hardwood flooring materials bonded with Bostik moisture cure urethane adhesives. From an "ease-of-installation" perspective, these samples appear to have the most important characteristics of being flat, straight, and we were able to rack them together well. The following Bostik Hardwood Products are recommended for flooring approved by the hardwood flooring manufacturer for use in a glue-down method of installation:
