Since you seem to be the new point of view, how would you compare them? What makes StormC your choice?
It was just easier to figure out how to use. I have full licenses for both and it was a struggle for me to learn how to use Cubic.
Mind you, I don't use either heavily, just don't always have the time to, but I found StormC easier to use.
And, like you, I'm, unfortunately, spoiled by by VS. I even have it set up to cross compile to the Amiga. Debugging sux, though, which is why I have StormC among others.
