I don't think there is much difference in the taste. All the quality fish I have caught this year have been whites. I don't know that you would target them any different, just depends on the lake your fishing. White crappie like it a few degress warmer and will spawn a little deeper (2-4') than blacks. By the time the fish move in to spawn, I would think you would get a mixture of both pretty close together. White crappie don't like the weeds and vegitation as much as blacks, so I guess you could target them differently that way.
