Has anyone driven both of these? How do they compare?

I haven't driven either.

The RR is pretty out of date when it comes to self driving tech (I suppose many RR owners would have a human as their "self driving tech")... probably also has the older gen systems for using your phone as a key... no theater screen... most other stuff appears to be pretty similar though, just much higher quality across the board. I expect the RR would have better ride quality and be quieter... is it (and by how much)?
