People buy the Rolls Royce because of the image( being the most expensive luxury car) or to be driven in, If they want the best drivers car, the Bentley is the one to go.
Even If they were the same price I’d always prefer the Bentayga to the Cullinan.
The Maybach is the underdog, the E-ABC is the best suspension on the market, nothing comes close.
The leather quality ( If you tick the right boxes on the Maybach) is on par with Bentley and Rolls Royce but the switchgear feels cheaper, I have to admit that.
Unfortunately the current S680 V12 is not available with this suspension, because this car has no 48V system.
The biggest advantage of the Rolls Royce is IMHO the availability of the V12.
