We have a detailed explanation of the differences between Band-in-a-Box, RealBand and PowerTracks here: https://www.pgmusic.com/salesfaq5.htm#9

PowerTracks includes some RealDrums with it. Whereas Band-in-a-Box has both Realdrums and RealTracks included, so you could automatically generate a wider variety of instruments. Band-in-a-Box for Windows also comes with RealBand, which is a program that is very similar to PowerTracks in its layout.
