I read some of the manga a few months back. A cool concept but not for me. The fights were ridiculously over the top which was cool but that's all there really is to it. Personally, I like a bit more plot. I'll still give the anime a try. It probably will be more fun animated.
I also watch these shows in my free time and it's always exciting to watch with proper storytelling. The best essay review also discusses these shows and how it impacts people in recent times.
