Like most other folks around here, I have purchased other DAW's and occasionally look at other DAW's. The only one I've been really comfortable with is Sonar. It is a mystery why it isn't the one that everybody talks about. Nothing else really has the scope of Sonar. Then I had a thought (it does happen).
What if Sonar was the new contender? Imagine if we had never seen Sonar and it was dropped on the music world as it sits today. Same price, same features. I think the recording community would be gob-smacked. No one would believe that a DAW with all its features could be released at a competitive price point.
I'm positive that Sonar's biggest drawback is that it's been around forever and we just take it for granted.
