Heh one thing hasbro has that takara doesn't is decent quality control, Takara MP Prime has really cheap plastic and due to the weight that they support(usualy around the feet) stress marks and breakages are common, Takara used really cheap plastic for MP Prime where as Hasbro used a much more hardier plastic, unless you are just going to keep him in the box and never open it, get the Takara version. If you are going to open and pose and display him get the Hasbro version, granted it has the shortened stacks, but really yuo don't notice them after awhile. It's sorta like when widescreen first appeared, you really noticed the black bars on the top and the bottom of the screen but now it's so commonplace you don't really notice it anymore, it's kinda the same with Prime's smoke stacks.
