My "New Year's resolution" January 2014 was to learn to use RealBand. That's still a work in progress. That said there's a few things I've noticed.

As others have stated it is quicker to build a basic song in BiaB then RealBand. BiaB does much of it's work as background tasks so you can plug in a few bars worth of chords and try them out. RealBand builds tracks from scratch each time before it starts playback. Your wasting a lot of time between track rebuilds.

If you're making a lot of project changes BiaB seems to be more resistant to file corruption than RealBand.

RealBand seems to be more resource hungry (cpu cycles and ram memory dependent) than BiaB. The more powerful your cpu and the more ram available for use, the faster RealBand operates.

When you are auditioning styles BiaB's eight track limitation means it's real good at replacing instruments as needed. RealBand doesn't replace RealTracks. New RealTracks are added but unwanted RealTracks must be manually removed.

My opinion is BiaB excels at choosing initial style, tempo and key signature, chord entry, part markers and bars required; in other words, basic song structure. RealBand is best for track specific tasks such as editing midi, selecting midi instruments, choosing RealTracks, changing the chordsheet to modify a RealTrack's althorithm choices, using effects and mixing.
