Tough decision. We have a Tiggo 8, X70 and Jullion in our household. I have not driven the Tucson. I bought the Tiggo 8 based on all the tech and 7 seats. However ride is very poor. Best ride is Julion but it is under powered and has lots of tech. Car belongs to my son who is in love with it. Fuel economy of all these cars is about the same of 9 -10 km/l in the city
The Sportage and Tucson are almost the same under the skin as they share the same platform. It depends on your preference of external looks. I found the Jolion to feel more like a sedan than an SUV or crossover. It is pretty low by comparison. You need to drive these cars for an extended ride, not just round the block.
