Hi,
I have used both. Studio One for many years too.
now i am completely on cubase again…
the reason is as follows:
Studio One has become obsolete ! 
We now have all the features in Cubase that have made S1 great:
more Inserts, Automation Bezier Curves, Audio Event Effects, ARA integration, VSTi pics and a new normal browser (right zone), track colours in mix console e.g.
and think about all the unique wonderful features/effects/VSTis etc. in cubase that S1 doesn’t have…
I have now uninstalled Studio One.
Cubase is DAW king. No doubt. 
BTW: the dongle is not the problem. that are excuses. Who seriously works with it in the studio doesn’t mind. fact.
regards,
C.
