While you haven’t specified which car you are buying, we assume this choice is for either the Hyundai Creta, Kia Seltos, or Kia Carens Clavis. Whichever the case, given your usage and requirements, we recommend the 1.5 IVT.
The Hyundai/Kia CVT gearbox, which uses a chain drive, feels more robust and responsive than others that use a belt-drive system, and the 115hp 1.5-litre naturally aspirated petrol engine feels more than sufficient for city or highway use. Yes, of course, the 1.5-litre turbo-petrol is more powerful and more exciting, but the 7-speed DCT gearbox is simply too jerky in low-speed use, which becomes frustrating after a while. In the long run, this gearbox will likely require more maintenance than the IVT, too.
