here's why *I* like RB:

1) you have MUCH more flexibility to PLACE sound, both audio and MIDI, exactly where you want to in a track

2) you have MANY more tracks available

3) you have multiple MIDI ports available (BIAB has 1)

4) you have more MIDI resolution if you want it

5) The ability to pick and add instruments as needed without loading a whole style at once is (in my opinion) easier in RB (although ver 2012 made it about as easy in BIAB)

6) The use of loops is more convenient in Real Band

7) You have more control over effects (maybe not empirically, but it seems more intuitive to me in RB)

8) if you are already used to other DAWs, RB's paradigm is pretty familiar already...

9) audio effects that make it easy to fade in and fade out instruments according to taste

10) many more tracks on which you can record your own playing (BIAB only has 2)

11) since many people take BIAB projects and develop them further in a DAWQ, RB is the perfect one to use because it is included with BIAB, and it natively reads all the same proprietary file types (not true of other DAWs)



I could go on, but my wife is looking over my shoulder waiting for me to take her shopping... But that's a brief overview
