There's definately a difference in design. Gintani places the cats in the position of the primaries, Challenge places the cats in the position of the secondaries. Gintani uses 300 cell cats, Challenge uses 200 cell cats. The placement of the "x" is different too. The resonators may be different sizes as well.
