Ive used Cakewalk products since 1998 when I got Pro Audio 8. In the last month or so I purchased several DAWs and have been working with all of them to some extent. For me, S1 is as close to Sonar as it gets and it is the only DAW besides Sonar to integrate the Console 1.
 
I have been having a blasty the last month moving projects from Sonar into the other DAW's to see how it all works but it look like S1 is where I am going.
 
Love Mixbus and Samplitude as well. Both great but just a few things on each will keep it from being my main DAW.
 
I purchased a touch screen monitor too so if ya know anyone who wants to buy 24 channels of Mackie Control let me know heh.
