Hey, Bien,
The Mios is the more upright model here because it is reversible. The Shine will be very comparable to the BJCMGT2, honestly - maybe a slight change, but truly just slight. Check, perhaps, the Joie Versatax which has a huge basket and is quite upright. Similarly, the [[cybex-talos-s-lux|Cybex Talos is an upright model with a reversible seat and a large enough (not huge) basket.
The ABC Design Avus is more upright than the City Mini GT2, also worth checking. The Valco Snap is also a rather nice model in that aspect. And I will also mention Peg-Pérego strollers as they are also on the more upright side (except for ultra-compacts like the Selfie).
