Ciaz vs DZire 2017 - which would be better

I want to buy Petrol Sedan <=10 lack budget (driving hatchback since 10 years). I booked new DZire 2017 ZXI AMT but not sure about decision. I found it’s Build quality not good. Have seen external tin damage and bent with hand press. also, internal cushioning under roof is also not good. Not sure about safety features provided and reduced weight.
Alternative, I found Ciaz Deta manual with comparatively good quality and luxury. But length of car is concerning me.
Would you please help me to select between Ciaz and DZire? Also, would you let me know any other alternative sedan?
My requirement
a. price range <=10 lack
b. Good shoulder and leg room for rare seat with rare AC vent
c. Good ride handling
d. Good built quality and safety
