i have gone through same dilemma couple of months ago.... i have driven both Grande and Civic Oriel, in fact i have owned Grande 2015 and sold it recently.
The decision entirely depends on individual preference and choices, both care have pros and cons. If you are resale and value conscious and considers a car as investment then choice is obviously Grande.
If you car is going to be driven on rough and tough condition road and load wise then again Grande is obvious choice.
If above 2 are not really a concern and if you want to have a eye catching experience with more advanced features like push start, electronic brakes etc then Civic is way to go.
Quality wise to be honest there is not a much difference, i have owned Grande and found substandard finishing so as the case with new Civic.
by the way i have opted for Civic.
Hope it helps.
