No first hand info on Tata-Fiat A.S.S. in Pune, but from what I have heard it is not bad!
I have too voted for Punto 90HP. It is the best diesel hatch available right now. Better than Swift. Car performs like a beast on highways and does not lack that much grunt in city as well. It all depends on if you are able to keep the engine boiling and ready to downshift when need be. For an engaging driver this is the best option
