I lovethe DID Hands, particularly those painted in a way that makes the look very realistic, you can even see veins under the skin. The same sculpts are also painted "flat flesh" and look terrible.
I also use only DML bodies. Like the variety in hands for groups but for a special figure I go with DID hands. In terms of gloved hands, my favorites are the old BBI German gloved hands...
As for DML hands I avoid mixing the relaxed hands and the others. I use the relaxed in pairs and like them a lot. For the rest use pustol grip in 95% of figures and avoid the rifle triger hands...
