I voted neither. I do like the look of the clear. However, assuming the oil pan is made of steel, I don't think I would do this because it WILL get chips, and the chipped areas will become little rust spots. If I am off base, and the pan is aluminum, ignore this. If not, I would go with clear zinc plating. IMO this would look good with the aluminum block, and be much more resistant to rusting when the gravel flys.
