Not an uncommon problem, but, all methods can make the same affect, and look perfect. For a box you'll need to strech the content in a special way, spheres made from lots of polys can be hard to handle, and will up a bit more resources.
You say they look bad, could be your general artist skills. But maybe you could use Tattoo or something similar (dunno if it's good for such a task) and just make a sphere.
Well, think some good tool for that task is needed (put on do later list).
Maybe I can fix a star algorithm, for making it all look the same in a box. Will be back sooner or later.
Edit:
Yes they are beautifull, but it doesn't seem like they were created as spheres.
