Please help choosing my first car

My budget is 12 lakhs,. This will be our first family car. I want to buy subcompact SUV. I have confusion between nexon cng, sonet and venue. I am more inclined towards nexon because I want safe car and I like it's look too. But sonet provide little bit more features but its build quality doesn't seem good enough . VENUE is over all good package but lookwise it's ok. Also mileage of 8-9 kmpl in city traffic is too concerning for me that's why I am thinking for cng of nexon.

Please give me some suggestions, id there's any better car. ( Not punch and suzuki cars)
