I, too, prefer to hand-plant CCs and find that aspect of SONAR more awkward today than it was under 8.5. Automation is also less convenient now, and I've been waiting years to see some basic enhancements such as scaling and inversion.
Yet despite my complaints I remain a fan with no intention of switching DAWs. Experimentation with alternatives has shown that every one of them has their own strengths and weaknesses, and none offer a solution that's perfect in every regard.
Far more important is achieving a comfort level with a tool that allows you to forget about it, to let it fade into the background of the creative process. If Cubase (or Reaper or Studio One or Logic or a Studer) does that for you then that's the path you should take.
For this complainer, however, SONAR does the job it was hired to do, does it fairly elegantly and - most important - doesn't get in the way of the process.
