I prefer wood of most any type, but I'm also a heritic in that I like the look and feel, of a well worn set of Pachmayr's on a equally worn service revolver, say a Model 10/64. They look like "serious business" I've always thought. I like Ivory on a blue gun especially, but have never owned a set of real ones.
On the other hand, I don't care for stag at all. No idea why, it just doesn't appeal to me.
