I like the way negatives come out in the developers I use with the film I use. They give me results that suit my taste.
IMHO, which developer you use depends somewhat on the film and/or lighting conditions, whether pushed/pulled, etc. óbut most of it is just your preference, what combination gives you the look that you like. That, as much as anything, can help give your prints a signature.
I think D-76/ID-11 gets used in schools and literature more than others because it gives consistently good, predictable results with just about every film. It's the vanilla of developers. It's easy to forget how good plain vanilla is (now I'm getting hungry!)
