Goku's are the only decent one. The other two look extremely cheap, probably due to the material creases and cracks you can see even in the promo shots. Considering they cheaped out on that I wouldn't want to find out what the true quality of the goku version is, they are simply the best out of what is shown.
EDIT:
Just looked again, you can see the same thing in the goku version it's just harder to spot because they are dark blue. Cheap garbage.
