If you don't mind paying the higher price for one, the Kia Seltos diesel would prove to be a better choice for your usage. The 1.5-litre engine delivers enough power for highway driving and scores well on refinement, too. The biggest advantage would be in terms of fuel economy.
Do note, if your region has a 10-year registration limit on diesel vehicles, resale value will be impacted some years down the line.
