Using both 1.3 prosmatic (myself) and 1.6 altis (Father's). Fuel economy wise there isn't much difference, for both city driving and highway. Driving in city both gives around 9-10 kmpl. On highway the average can touch 15.
Fuel tank is small in CITY (42 Liters) so that's a setback compared to that of corolla (55 Liter). Driving comfort wise Corolla is also better but honda isn't that bad. 1.6 is quite good and i really enjoy driving it, never disappoints while over taking even with luggage and all seats occupied, while city takes some time( what else do u expect from a 1.3).
I am using my 1.3 pros city since 2013 and have nearly 50k on the odo, and I am satisfied.
But if your pocket allows you, don't think of getting 1.5 aspire, 1.6 is the best option. If u get 1.5 aspire, you will again be stuck to 42 liter engine and a bit stiff drive compared to that of corolla.
(I haven't driven 1.5 aspire so can't comment on it's engine response)
