Which convertible carseat should I get?

We're researching now as to which convertible carseat we want to get, we don't need it now as our baby still fits in her infant seat.

Our top choices are: 1. Maxi-Cosi Pria 2. Nuna RAVA 3. Graco 4ever

We're open to other suggestions. We drive a Toyota RAV4 if that helps determine a good fit/size too.
