Dream Ball has the nice lavender shades and pink (plus a much better opening animation for her, assuming they didn't change it too much from the 3DS versions), but Heal Ball has the pink, purple, and white altogether plus it also has them arranged in a way that's very complimentary to her bodyshape.
For a shiny one, pretty much the same thing but if you really wanted to the heavy ball is also a minor option due to the greyish blue of the top.
