Here’s how they compare to each other:
Vader: Circular peghole, round button support feet at the bottom, and flimsy plastic.
Clone Trooper: J-style peghole, square support feet at the bottom, and sturdy plastic.
Target 5-pack: Vader-style case with heavier plastic weight about the same as the Clone Trooper.
The Clone Trooper version is the best, and would have been my choice for issuing the five-packs from. Still, most figures are a very, very tight fit vertically. Each time a figure is placed into the pack, it feels as though you are risking bending the card. In order for the cards to fit properly, you must insert the card from the top first, slipping the card underneath a small plastic lip (the source of all the Vader card problems). If you don’t make sure the card is sitting flush beneath the lip, when the backer piece is inserted, the card will be bent. Even still, the card wobbles loosely inside the case since there is no point of contact, aside form the very top point, between the cardback and the joined front and back layers of the case.
Crappy.
