My sister just traded her X3 xdrive30e for Q5 45 P+. Honest opinion is the Q5 feels like it is better built than the X3. Driving dynamics is better on the X3. Some features are better and included on the Q5 with P+ like the sound and ACC. But some stuff lacking like ambient lights and navigation/digital cockpit without going Prestige.
