BiaB and arranger keyboards are similar tools, but they do have significant differences.

BiaB can have more patterns, and since it knows what the next chord is going to be before it plays, if the style author is good enough it will play an appropriate variation at the right time.

Arranger keyboards often have tighter unison parts, especially during rolls (although there are fewer of them), and extended intros and endings.

Both tools having different strong points might make one or the other better for a specific song.

Personally, I think having more choices is a good thing.
