1.4 CVVT suction engine in Kia ceed Sportswagon recommended?

Hi, for a family member I think about buying a Kia Ceed Sportswaggon. I can’t decide yet about the engine variant. Kia had a 1.4 CVVT suction engine with 99 hp available until 2019. What about this engine? After all, the engine has Euro 6 and the green badge. So you can drive to the city center. What about the durability? (In the past, suction engines were very robust) Alternatively, the 1.0 T-GDI with 101 hp would be considered. The family member who drives the car tends to drive more steeply. Is the fuel consumption in this speed range significantly different at all?
