Well, first of all, fillers are unavoidable. The animators would rather make some content while the mangaka wrote more content for the main storyline. The decision to make fillers lies with the animators, nothing the fans say will change that.

The Zanpakuto arc further explained the relationship between Zanpakuto and Shinigami. We got to see Chojiro Sasakibe's Zanpakuto power. We wouldn't have found out about his power until the last arc.

The Reigai arc expanded on a topic that was forgotten for quite a while, the Mod Soul. This was another interesting arc where characters had to fight stronger version of themselves. The battles could've gone either way. The main villain of this arc had an interesting ability. I enjoy characters with interesting abilities. From the moment he/she uses their power, I think of possibilities of what their abilities will do or how they will work.
