My favorite developer (at the moment) is Gevaert G262 diluted 1:8, then left in a tray to die overnight. Beautiful warm tones, and a reduced contrast which is a real help with some of my negatives. Exposure times are 2 to 4 times "normal", in that way it's a bit similar to lith printing. Except that the shadows don't run amuck.
Next week I'll be trying a few other developers, so my preferences are bound to change.
