Thought I'd update the forum, possibly to assist some members in the market with a similar confusion.
I ended up buying a 2011 manufactured, 2nd gen Prius (2014 reg) at around 15 lac. Got her a new set of shoes (Yokohama AE50, 2019 manufacturing year, purchased directly from Shaikh Brothers) and so far she's been with me through rain (literally) and sun.
I drove the Fit Shuttle (2nd gen) while I was looking for a car. The difference between the two is negligible in terms of driving experience (Fit offering more torque). Prius' is more comfy to drive I felt.
Space is slightly cramped at the back if you're tallish, no problem for an average height person.
Fuel economy is currently 20kmpl (+- 1kmpl) depending on driving style and the blend of city/hwy mix. I have taken the car to Hyderabad numerous times without any issue Masha Allah and there's been no issues with either the battery or the ABS so far.
I do however get slightly envious of the Shuttle's space sometimes and Freed's quirky driving seat but I guess practicality wins over shauq sometimes
