It also depends on "what you do with your DAW?"
For myself, I play in a band that has written, performed, and played for many years. We recorded to tape for years. So our workflow is more similar to the old classic studio in the tape era. We play "basic tracks" to sonar and overdub parts after that.
Pretty much all of our music is "us playing instruments and recording them." Our writing is all on "instruments," we write by playing guitar or keyboards or some instrument. None of this involves our DAW at all, other than to maybe record some ideas for later reference.
This is a much different workflow from someone who does EDM or sequences a lot with midi, groove clips, and the like. It's also much different than someone who writes music via a "score" and produces things from there. Many of these people write using their DAW, putting together the music, moving the arrangements around in the DAW, etc.
So different DAWs are stronger at one style or the other. I know that for our workflow and what we do, Sonar is excellent. I also own Reaper and could do everything there as well, but I prefer Sonar.
If our workflow was different, I'm not sure. I don't do that so I'm not as aware of the issues and comparisons of Sonar vs Reaper for those situations. But it's something worth thinking and studying about.
