Which is cheaper to own over 5 years, the BMW iX3 or the DS N°8?

EVcarsguide estimates a real-world motorway range of about 293 miles for the BMW iX3 and 285 miles for the DS N°8 - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. Both rapid-charge to 80% in a similar time, around 21-27 minutes.
Which is easier to park and drive in town, the BMW iX3 or the DS N°8?
