The only thing good about this chocolate is its packaging.
The taste of crushed oreo biscuit inside the outer layer of chocolate does not seem to fit here. A routine cadbury dairymilk tastes far better than this chocolate. Its kind of messing with the real quality and taste of cadbury.
Now about its alternative, according to me cadbury dairy milk crackle is perfect replacement for it rathar than try to create new flavors they should try to make the pr-existing products better.
