No experience with the Outback, but my son has a 2014 Impreza with the CVT. As CVTs go, it's not horrible, although I think CVTs generally suck. I've driven several Nissans with them, and they were considerably worse in terms of sounding and accelerating like sewing machines. The Subaru CVT is, IMO the best of the lot. But in the land of the blind, the one-eyed man is king, as they say. I would never get a car with a CVT, it would drive me mad.
Other than that, the Impreza has been a good little car, better handling than you'd think, reliable, and a real bargain. But I can't comment on the Outback one way or the other.
