Hyundai i20 or i30

Hello all, I'm currently looking at buying a new car and have settled on either an i20 or i30. My budget is around €8,500 so the below cars are two of the frontrunners for me at the moment.

My main concern is whether the i20 might lack some speed on the motorway. If speed isn't an issue for the i20, which of these two cars would you guys recommend?
