Which Maharaja Express Route Is Best for Exploring India?

I'm planning a luxury train journey through India and have been researching the different Maharaja Express Routes. There seem to be several itineraries, including The Heritage of India, The Indian Panorama, The Indian Splendour, and Treasures of India.

I'm particularly interested in visiting destinations such as Agra, Jaipur, Ranthambore, Udaipur, Jodhpur, and Delhi, but I'm not sure which itinerary would provide the best overall experience.
