The difference is the lens version included in the kit: the newer option comes with the EF-S 18-55mm IS II instead of the older EF-S 18-55mm IS.

From the community info, both lenses are essentially the same in the ways most buyers care about: same focal range, aperture, minimum focus distance, filter size, and no optical redesign. One answer notes possible stabilization improvements, but another states there were no changes to the optical formula or Image Stabilizer and that the main differences were minor cost-cutting/cosmetic changes.

So in practical terms, image quality and general use should be very similar. If the camera body is the same, the choice between these kits usually isn’t a major one unless there’s a meaningful difference in price, condition, or included accessories.
