Stop Super Sentai severity! Protect the Power!
There is no better series, its just whichever you prefer. They all have their ups and downs but its just a show. Power rangers wouldn't have existed without sentai, and sentai wouldn't have gotten famous overseas if power rangers didn't introduce us to the franchise in the first place. It equals itself out.
What's the point of you guys arguing which is better at the end of the day both shows are about guys in tights fighting evil.
One of these days, every Toku fan will.
