I thought that Polymax Fine-Art was the best modern (post-1980) paper that Kodak ever made. It was easy to make good prints with it, and they looked great when finished. When they discontinued it (along with all their b/w papers) in 2005, I used up my stock rather quickly. I lacked the means to buy and store a large quantity of it, just as well. Luckily, Ilford MG IV was easy to learn, and was a fine substitute.
I am a bit sorry that my old employer's product hasn't lasted 15 years past its sell-by date... but it was never meant to do that.
