What the numbers actually say

There is 0.6 l/100 km between these two (1.3%). That is inside the 10% tolerance of declared figures, so on fuel alone neither is the better choice: at 120,000 km a year and an assumed £1.40 a litre the gap would be about 720 litres a year (£1,008). The declared figures for one of them alone span 6.7 l/100 km across its configurations, so the specification ordered matters more than the choice between these two.
