As usual I disagree with the above, but It is one example of Hasbro trying to please the majority of fans for a change.
The advantage of Hasbro's releases are that they are far more toylike, and don't have any diecast to chip paint from, or chrome to wear of.
That said if you put a Takar release next to a Hasbro one, most of the time the Takrara one looks a lot nicer than the Hasbro's. Not to mention they tend to be packaged a lot nicer. And this isn't just a recent phenomena. Going back to the Robots in Disguise the Car robot brothers releasesd by Takara were of much higher quality than the Hasbro ones that suffered from spliting rubber and only partialy transparent headlights. I personaly think its the japanese mentality toward customer service and satisfaction.
FFN is correct that there are more Hasbro toys out there than Takara, but that's kinda the point Hasbro go for quantity not quality.
