Control is one thing, but writing the best musical parts that you can is even more important in my view.
I am just finishing up a re-orchestration of a piece I produced a few years ago straight into a DAW. It was a good piece, and I liked the audio output from the DAW. In StaffPad, I am redoing the string lines and counterpoint, preparing parts for performance. These new updated parts I could have never have imagined playing straight into a DAW. The piece is much more musical now, and the output sounds better than what I produced in the DAW.
For me, it is much easier to write (and re-write) the individual parts from a musician's view when using StaffPad, vs playing directly into the DAW. I think this is part of what makes things seem more musical.
Once you have the music written, there is still quite a bit you can do, exporting from StaffPad to a DAW for further processing and refining levels if you want that extra 10-20% of quality.
I suppose you could achieve the same with pencil/paper, then entering into your DAW if that is your preferred workflow. StaffPad isn't for everyone, but it has been tremendous for me.
