1. Mighty Morphin Power Rangers knew how to do serialized storytelling. They connected all their shows together in one cinematic universe. They did it at least a full decade before Marvel even existed. They also knew what to edit out for the Western Audience. This led to Power Rangers making $15 billion dollars over 10 years in merchandise sales.

However the owners of power rangers changed several times in the 2000s. From Saban, to Disney, back to Saban, and now to Hasbro with Netflix support. With so many changes in ownership, the TV show had no clear direction. Directors and Executives and writers constantly changed their ideas. This has led to inconsistent stories. And the franchise also suffered from forced DEI diversity. They hired actors based on their ethnicity and not their talent.

2. Super Sentai has some really cool ideas (powered suits, martial arts, and giant robots fighting monsters), but the company that makes Super Sentai is extremely rigid. They are unwilling to adapt or incorporate Western ideas (such as serialized storytelling, more mature storytelling, or letting actors stay on for more than one season). The Sentai stories got more and more zany and wacky to appeal to the dwindling Japanese fanbase, and the writing focused more on appealing to children under 5 years old. The acting stories were very bad. They started making stuff like (Pic related), and eventually becoming a shadow of their former selves. The ratings and toy sales plummeted which lead to Super Sentai being almost canceled several times. It's future is unknown.

Another issue is that Super Sentai Executives at Toei seem to have a grudge against Power Rangers. Several interviews were done over the years where they said they grateful that Power Rangers is successful and shares profits WITH Toei. But they don't understand why Power Rangers is a success but the world rejects Super Sentai. Some even said it makes them upset that the world likes Power Rangers much more.
