In my opinion, both have their merits. The anime brings the characters to life with animation and sound, but the manga allows for more imagination and detail in the panels. It really comes down to what you value more in your entertainment.
Well, the Bleach anime story is really exciting. It begins with Ichigo's ordinary life being turned upside down when he gains Soul Reaper powers. He has to balance his normal life as a high school student with his new duties. In Soul Society, there are political intrigues and power struggles. Ichigo and his friends face powerful enemies like the Espada, who are Arrancars with great strength. And as the story progresses, Ichigo discovers more about his own powers and his connection to the Soul King.
I'm not entirely sure if 'bleach' specifically watches anime fanfiction. It depends on what 'bleach' represents here. If it's a reference to the anime 'Bleach', the fans of that anime might watch fanfiction in the form of written stories or even some fan - made animated shorts. But without more context, it's hard to say for certain.
For me, the manga is better. It allows for more imagination and often has a purer story without the constraints of animation production. But the anime has its own charm with its music and action sequences.
In my opinion, it's a matter of what you value more. The anime can bring the characters to life with movement and voice acting, but the manga allows for more imagination and detail in the panels. So, it's not a straightforward comparison.
