It is pretty well accepted in the RR collector world that the 20K series SZs are, overall, the most reliable.
The very earliest ones are very similar to SY cars, with the exception of having gone to HSMO brakes/hydraulics, in markets where carbs were still being used. The fuel injection systems are beginning to show their age on all cars of that era, some more than others.
As has already been mentioned, as time marched on, and particularly with the introduction of the 30K series, the amount of electronics and number of ECUs increased dramatically. One of the strong points of RR/Bentley of this era is not, in my opinion, the reliability of their electronics (that's not a strength, really, of RR/Bentley in general, even reaching back before the 30K series SZ cars).
I have never been able to warm to the SZ series styling. The craze for "box like" during the era they were produced has caused me to remain cool to a very great many cars produced at that same time. And the quad headlamps on the US Spec versions is just not very pretty, to my eye. All of this being said, "Chacun à son goût!"
