Buy alto instead

I have owned i10era 2010, Figo petrol 2010, beat petrol 2010 before buying Celerio. Pick up is very less compared to other vehicles mentioned and even compared to alto 800. When I asked ASC they says so many owners complain about the low pickup. Good points are space in the cabin and ac. I'm getting mileage 14Kmpl in city and 15 on highway which I feel very less in comparison to my beat which is more powerful and peppy gives 15. Being a smaller 3pot Celerio was expected to be more fuel efficient, which it is not. Not happy.
