I would suggest that if you've already become somewhat familiar with BIAB, take advantage of the learning curve, great tech and forum support, and cost factors (it comes free with BIAB), and spend time to learn RB as your DAW until you get to a point that it cannot do something you need to do. I have found that it is very capable indeed as a DAW, and I suspect that it will be quite some time before you ever get to the point that it cannot accomplish what you need to do. At that point you have, at additional cost, some choices, and you can then go there if you feel the need.
