I was pretty nonplussed about Rapture Pro at first, which is why you didn't see me posting much initially. I didn't want to complain and later find out it was just unfamiliarity.
It was sort of half and half. There were definite issues, which have been mentioned in these threads, but there was also quite a bit of pilot error/misunderstanding.
The more I use it, the more I like it. The Performance page is turning out to be the hidden gem for me by consolidating a lot of parameters in an easy-to-use way. There are definitely some issues, but I suspect they'll be fixed sooner rather than later. I don't think it will take too much to make Rapture Pro the way it's supposed to be.
Meanwhile, I must say I think I'm coming up with some cool sounds...
