I would think if you shot the same scene twice and exposed and developed each negative for the optimal time for the paper involved, you're results would be a tad different. From what I understand, and whitnes with my own negatives, the ones destined for AZO have a very different tonal range than those made for enlarging paper.
From my own prints, I have got to say the few that I have done on AZO / MS Amidol have been great. Wonderful tonal range, and deep blacks, etc. I also have prints made on enlarging paper that I am equally pleased with. (and plenty with both that I am not pleased with! )
I'm not trying to knock what you did, I just think before everyone jumps the gun, the testing methods need to be addressed a bit.
