EVcarsguide estimates a real-world motorway range of about 189 miles for the Smart #3 and 171 miles for the Zeekr X - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Smart #3 goes roughly 18 miles further between charging stops. A rapid charge to 80% takes around 30 minutes in the Smart #3 and 20 in the Zeekr X, so the Zeekr X loses less time at each stop. So the Smart #3 stops less often while the Zeekr X stops for less time - pick on which you would rather do.
The two are within 8 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 564 mm of total clearance for the Zeekr X and about 556 mm of total clearance for the Smart #3.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Smart #3 and 90% for the Zeekr X. That gives the Zeekr X a modest edge in retained real-world range. The Zeekr X's LFP-type pack tolerates daily 100% charging, while the Smart #3's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
