Swift Dzire can be your risk less choice here. I like Indigo Manza a lot as it gives you a lot for the money you are paying. Fiat's cars do not have great resale value, so not sure about Linea otherwise its just a great car.

In short, if you are vary of resale value, consider Dzire or Manza. I would say compare their features side by side and see whats giving you more for your money, test drive both and see which makes you more comfortable.
