Whatever China's regime is now, it is the expression of a population with a much more collectivist spirit than the West, a population that overall (i.e. a small dissident minority aside) is willing to submit to the Party in the name of social stability. The West is a lot more individualist, and a revolution under those circumstances is likely to be much messier. The point is that it probably wouldn't neatly land on a specific model, Soviet or not, but would first involve immense turmoil and infighting like revolutions usually do, and after that it still probably would never reach the effectiveness of China's post-Mao model.
