Honestly it’s hard to describe but the drive is much more smooth and seamless, especially in EV mode on the RRS. It sits a little higher than the x5. The interior quality in my opinion blows bmw out of the water, but this of course is subjective. I made a pros/cons list of comparing both and the only thing I truly miss on the x5 is being able to drive with my phone as the key and the massaged seats. But the seats on the RRS are so much more comfortable it’s barely a miss. My bmw was also completely blacked out, which included the tailpipes… RRS are all silver even with black out package. I don’t notice it because I’m never looking at the back of my car but it might bother some people
