Doopys get heavy fast, holding one for a few hours straight kinda sucks. Hyperfirm look cool and are super light and will rarely break when dropped. Doopys will loose a few parts when dropped. Kids love love to hold the blasters for photos. If they make pew pew noises like the Hasbro, you'll be a rock star. The Rubys painted black is kinda boring. I only holster that one while I'm also sporting the DLT-19. I have all of these and that is my experience.
I won't give any comments about details or accuracy and leave that to the pros. Troop on.
