Logan is better amongst the 3 in my opinion. Its price is very competitive.  It gives good mileage; 15/16 in city & 20/21 on highway.  It is very spacious & comfortable car.

According to me the best bargain presently is the Fiesta 1.6 "fida edition" which is priced at 6.6 lacs and it has a lot more than these features you mentioned here, like the leather seat covers and leather door trims, the alloy wheels, turn indicators on ORVMs, and most importantly the 1.6L engine(101 bhp), a nice fire cracker to buy this Diwali. Go for it. OR among these the Logan I think is a good buy.
