I'm probably a party of one here, but I like the darker, walnut-colored wood on the blued revolvers, and the medium or lighter, maple-colored on nickel finish. I've switched around grips on my various revolvers just to see what looks best to me. (Don't worry, none of them were "numbered" to the guns. I only LOOK stupid.)

But Caje is right - what ever YOU like best is the final answer.
