The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Adiva AD3 400 has a 770 mm seat; the Can-Am Spyder RT sits at 755 mm — a 15 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 77 cm for the Adiva AD3 400 and 76 cm for the Can-Am Spyder RT.
That makes the Can-Am Spyder RT the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Adiva AD3 400 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.
