Melodyne was the main reason I stayed with Sonar when they added it. I still haven't upgraded to the full version. I may do that this time.
This software is pure magic.

Yup...
 
One of the main reasons I originally purchased Studio One v2 as a second DAW was for its ARA integration with Melodyne.  And I did make very good use of it.   But when ARA was added into SONAR, that really changed things for me by allowing me to stay in my DAW of choice for those same tasks.
 
Now add Melodyn 4 into the picture...  and wow, especially the Studio version with its multi-track capabilities and other new goodies.     I just received my upgrade license info today.
