DIVISION was part of the gazettE's struggle period. While it is better than TOXIC, as a whole, the album was very flat and lifeless from production right down to song composition. Hell, i didn't even think Reita existed on that album or if Uruha or Aoi knew what it was to have separate parts anymore. I will admit that the finale show was quite enjoyable though.
BD seems to be the superior album because of how close it is to the bands previous work, and how it corrected on the errors of the previous two albums. Also, you can get the vibe that the band enjoyed making BD due to how "fun" and creative the songs were. The previous two albums sounded like it was a chore.
