I scale the elements the same way I want the detail amount to be. The uvs are fine for what I plan on doing what I need to do with them. The skin elements are smaller as they have less detail. The cloth is bigger. But the way I pack them is to have better pixel flow and so they are easier to texture since I separated the cloth elements from the skin elements. If I was to use the second one then I would have pixelated normal maps and textureing it will be a bitch.
