It is great that you wish to buy a new car and we are happy to be a part of your new car purchase. The cars that you have selected compete neck to neck. Brezza is a "Maruti" that means you get least maintenance, more mileage and better resale value, technically it is more economic. However, it misses out on power, looks and built quality. Ecosport on the other hand has got enourmous amount of power, has got better built quality but misses out on mileage and maintenance. Thus, if you are looking for a car which is readily available, you should choose EcoSport as Brezza has a huge waiting period and if you wish to buy something which is more "Economic or pocket friendly" go for Brezza.
