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.
Also, the character development in the fanfiction could be very different. In the original Bleach, Kenpachi is mainly about becoming stronger in terms of his combat skills. However, in this fanfiction, his development might be more centered around his relationship with Ichigo. He might learn about things like love, compromise and self - reflection which are not really part of his original character arc in the main story. And for Ichigo, he may have to deal with a whole new set of emotions and challenges that are related to this relationship rather than just his duties as a Soul Reaper.
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.
It depends on personal preference. Some people like the manga for its original art and story pacing, while others prefer the anime for the added animations and voice acting.
