I own the 2015 model. I am using them just as much on slopes as i am hitting rails on them. The wider platform paired with rocker profile makes them somewhat usable in pow, but i wouldnt go anywhere other than some sidecountry with them. However, I dropped some cliffs as well as ridden quite a bit of trees on danollies, mostly when i would mess uo my ski choice for the mountain... it just requires a bit more work than wide pow sticks. On the groomers, I feel comfortable at any speed honestly (I can manage to carve down Gran Risa(worldcup downhill piste) in icy conditions, but with a lot of chatter in the rockered sections... But it is totally doable). Rails are obviously the terrain they excell in, no need to piont that out. I would absolutely mark them as an all mountain jib twin better suited for soft conditions.
