I've only tried two kinds of developer so far in my home darkroom. First was an Arista brand from Freestyle, and it seemed to work fine. And then I ordered some Nacco Printol 12, and it works good too.
For papers, I am currently loving Bergger VCCB FB in semi-matte. I bought a sampler pack of Luminos products, so it's been fun trying those out. I really liked the Rough Art RC, and I wish it wasn't so expensive. Ilford papers are usually pretty good, but I haven't tried the Multi grade FB, I don't think. I was given a big box of Kodak RC in glossy and I didn't care for it, but of course I used it all up, since it was free. But I'm glad it's gone and I can try new stuff. I just got a pack of Agfa RC to try out. I also have a pack of Agfa 111 FB and I liked it so far, but only printed once or twice on it.
