I think a lot depends on how you 'grew up' with BIAB. I started on floppies and midi only and got PowerTracks bundles with BIAB for free.
Learning to use both programs I found some functions not available in BIAB were easily managed in PT. So my workflow was get as much laid down in BIAB and then move to PT to produce midi backing tracks for the duo i played in.
Since then BIAB has acquired many many more functions, but so has PT in becoming RB. Building on my skills with PT, its natural for me to use RB for 'heavy lifting'. RB is still for me, more transparent and obvious than BIAB. Legacy track? Melody track? soloist? utility track? no need to search - all the tracks are in front of you.
I know it's second nature to Jim and Charlie to stay in BIAB but for me RB is so much easier. Nothing hidden, fx easily added, a mixer that looks like a real life mixer..... and all the functionality of BIAB if i need it.
so with RB as my DAW it's a workflow i prefer. and if i get stuck, the program is so easy and familiar I can usually work out how to do things. but not always - and that's why the forum is so useful!
