The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Puch Maxi Sport has a 483 mm seat; the Yamaha LB 70 Chappy sits at 710 mm — a 227 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 48 cm for the Puch Maxi Sport and 71 cm for the Yamaha LB 70 Chappy.
That makes the Puch Maxi Sport the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Yamaha LB 70 Chappy gives taller riders more legroom and a more open knee bend. Load your own height and inseam into the simulator to see exactly how each one fits you.
