Logan & Manza - both are VFM cars and from that aspect Manza scores better
Fiesta - fun to drive car and if you are looking for a car purely from a driver's pleasure Fiesta is good. But generally the Ford cars are expensive to maintain in the long run and Fiesta rear seat comfort is not good enough compared to any other sedan as it is crampled
Verna - good initial pickup but high speed dynamics are not good. Ride and handling leaves a lot to be desired
Manza - good VFM car but worth waiting for 6 months to settle down. Uses the Fiat 1.3L MJD used in Linea, Swift, Dzire, Vista etc
Linea - When you are open to considering even Logan I would stronlgly suggest you to consider Linea as Bharadwaj said.
Linea comes with 1.3 MJD and has the best acceleration in the usable range - ie above 30 KPMPH. Has good enogh low end grunt for easy City driving and has breathtaking performance on highways. Gives excellent mileage - at least 14+ in City and 18+ on highways with AC, however badly you drive. Ride and handling as well as roadgrip - best among the sedans.
Price - no other sedan gives so many features as Linea with a solid build quality
Features - no other sedan at that price point gives as many features like Linea - Blue & Me, My Car, Follow Me, Foldable Key, Rear sun curtain, Rear AC vents, boot lamp, Alloy wheels, Climate control, rear fog lamps etc etc
Support - FIAT has bad image due to experience of people during Uno, Palio and Siena days. But from Linea and Punto onwards they are very serious and the service hs improved considerably. Linea has the service freq of 15000 KMs - highest among sedans compared 5000 or 6000 of other sedans. Also their spare parts are cheaper than Fiesta, Verna, City etc.
Resale value - This is something that needs to get established for Linea over a peiord of time and is expected to be good considering the interest sales, low maintenance etc
