I use my arranger for recording, and I'd like to think that my audience is going to listen to my recordings repeatedly, so the more varied and vast my style collection, the better. I try to never use the same style in more than one recording.

To that end, I just purchased Band In A Box 2014 to try and vary my recordings a bit. I'm quite pleased with my first attempt at using it in the studio. The Real Tracks audio clips are pretty cool, and because the software knows in advance what chord changes are coming, I find the bass lines are more "human" than what the arranger can do. Of course none of this is useful for live performance, but still fairly impressive technology, I think.

It's really quick to sketch out a tune and print a lead sheet too.
