In the past 65 years I have used many developers on many films. Even at the beginning, I had some idea of what results I wanted, and I found that most of the developers could give me what I wanted, but maybe not on the first roll or two. The difference between them was largely in the convenience of use. From age 40 on I played in symphony orchestras in the Tidewater VA area and would take pictures of guest artists at rehearsal, rush into the darkroom (upstairs bathroom was "Bath by appointment only") and have prints to give to the artist the next day at the concert. I needed a developer I didn't have to fuss with. There were several, including D-76 replenished, D-76 diluted, Acufine, Diafine, and a number of home-brewed concoctions. I got good photos from all of them.
My criteria were ease of use, consistency of results, and good film speed. These were, of course, unposed available light photos. Anything else I could finagle in the printing.
If you learn all the ins and outs of D-76, you will have a knowledge base, most of which you can apply to any other developer. Not the actual numbers, mind you, but the methods for learning the numbers. There is an adage "If you give a man a fish, he eats for a day. If you teach a man to fish, he eats for the rest of his life." You can teach yourself how to fish for the numbers like time and temperature.
Enough lecturing.
