I use both. Start in BIAB with chords and a few RT's, then over to RB for more tracks (multis and midi). It usually ends there but on some songs I take it further and go over to Reaper or Bandlab Sonar. I do most of the "work" in BIAB because it generates much faster and I tend to slice and dice styles and RT's.
