If you go through the History of Bentley and Rolls Royce, Bentley was the sister firm of Rolls Royce, which aim is to produce Luxury Sports cars. In 1998 both of brands got separated and Rolls Brand was bought by BMW due to already a 3% share in firm and Bentley was bought by VW ... We cannot compare Rolls Royce and Bentley with each other .. Bentley is basically for a Luxury sports car not a Luxury sedan ... No doubt both are still Hand made ... regarding Maserati we cannot compare it with Bentley and Rolls Royce...
As for example here in Saudia, there is less number of Rolls Royce as compared to Bentley, if Bentley passes with you people not give it as much attention as compared to Rolls Royce... when I was in marketing team, I went to one area for survey of projects, I found 10 Bentley and 1 Rolls Royce... All Bentley's are parked outside just with shade on top, but Rolls Royce is parked in full packed shade, even in front of same house....
