I fully understand that this is a very subjective question, but is there anything close to a universal developer that satisfies most needs ? Mine would be HC-110 or lately Ilfotec HC for the sheer versatility that they offer. Pea soup economy coupled with high performance is a winning combination. Want a 3 stop push and it will do it. Vary dilutions and effects like stand development or semi stand are easily possible. It may be the swiss army knife of developers as someone said (Covington maybe).
