In addition to starting something from scratch, a better way to evaluate many features is to download a demo song (from the start screen), and work around the GUI. Scratch Pads and the Arranger Track will not get justice if making a song from scratch during the demo period - with a demo song you can start messing with those immediately.
There are hot spots similar to the smart tool within SONAR, but they also do not equate 1 for 1. Additionally, they also have hot keys you can press and hold to shift tool functions (dependent on view you are working in). MIDI implementation is a bit different in some respects, but PreSonus also made it clear that they have proprietary "MIDI" internally to bypass limitations of MIDI alone. I am not a heavy MIDI user, so cannot speak in great depth to what pitfalls lie in that area (I also do not use Kontakt).
The niggle I still have is no track templates as they are implemented in SONAR.
