I've been a huge Cakewalk supporter over the years and I've tried Sonar but I can't seem to get used to it. I guess it's because I've been using Pro Audio for years now and I don't want to let go! LOL. But Sonar seems really good, some of the features and layout are sick. I would use Sonar but probably the only thing I don't like about it is the audio editing. I think now they call it "slip editing". Anyway, with Pro Audio it's so easy to chop samples, with Sonar it looks more difficult. If anyone is more familiar with Sonar's audio editing capabilities, let me know exactly how it works!
