Well, a difficult pick in my view. And an almost excellent choice you have put up here.
If you want comfort, pick, acceleration, braking each and everything is there in axio. Spare parts are easily available but expensive.
The only thing that matters is to find a clean and maintained axio in specific price range.
On the other hand, you got city. Its 2015 model. New car. The comfort , braking, acceleration and pick not even near to axio. But the only good point is its newer car. Parts might be cheaper then axio.
Both the cars have almost same resale value.
Both cars easy to maintain.
The only thing iwill give my vote to city will be newer car.
Rest any day axio.
I have used both.
