The paper speed you get depends a lot on your enlarger and the VC filters or diichro head that you use, so it can be difficult to predict exactly how other materials will behave with your system. I've used the Agfa papers and Adorama's house brand of papers and can make a valid comparison between the two from the results I get in my darkroom. I use Kodak's VC filters in an Omega D4 enlarger with a dichro head and develop the paper in Dektol, usually diluted 1+3. The Adorama papers are about the same speed and have a little less contrast, about 1/2 grade, against the equivalent Agfa papers.
