I saw a post recently where someone had "mirror polished" a straight razor. In the before pictures, deep rust pitting was visible. It was not surface rust. In the after pictures, true the blade shone nicely. But, the pits of rust could still be seen. It was much less visible, and in fact most newbies would not even notice them they were so small.

This illustrates my biggest reason for preferring the natural look. Nothing has been hidden, either purposefully (not too often here, I don't believe) or inadvertently during refurbishing.
