I demo'd the Turbo Dream two weeks ago, it was a really fun board to take most places on the mountain. It turns very very easily, and it's pretty stable for a flat board. I felt like it would be a really good board for a beginner or freestyle rider.
However, it didn't hold an edge on steeper, icy slopes at all. I felt like icy terrain was its biggest weakness. Compared to the cambered boards I demo'd (Custom X, Jones Flagship) I was much happier on one of those when conditions were steep and icy.
I think the Slayblade would be more comparable to a freeride board, but I didn't demo it. In the end I like my current hybrid rocker/camber board (2011 Flow Infinite) more than the Turbo Dream. I'm very interested in the Raptor and will probably get that one. My riding goals are more speed/freeride oriented.
