FWIW, I did try both, but the thing that killed off Mixcraft for me was not having sends on busses, only tracks.
Otherwise I agree with others here that Mixcraft was a nice DAW.
Studio One is what I went for in the end, although I will still be using SONAR as my primary DAW, until it croaks. But even Studio One has it's limitations.
Like I said, you need to try both to see how they fit in with what you do, and how you do it...
