Tata Tigor CNG vs Hyundai Aura CNG: which is a better city car?

I am planning to buy a new CNG car majorly for city driving in Mumbai, so boot space isn't a concern for me. Is the Tata Tigor a good option compared to the Hyundai Aura? I am confused between the two since Aura is available in only one version and doesn't have many features. Should I consider the Maruti Suzuki Dzire instead?

Autocar India says: The Aura's engine is smoother, you will get more range out of its 65-litre CNG tank than the Tigor's 60-litre tank. And, in general, the Aura feels better finished inside. It doesn't get some features, but covers the basics well. So unless features are what you're after, the Hyundai Aura CNG ranks higher than the Tigor. The Dzire, although the most expensive of the three, is the better CNG compact sedan in terms of space, comfort, performance and efficiency. So if your budget permits, it is the one to go for.
