For what its worth I've flown on Swissair 100's into LCY. Beautiful cabin experience, spacious, clever more convenient overhead bins, bigger windows, spacious washrooms too. Comfortable seats. All in all a really pleasurable passenger experience.
I can't wait to fly on the new CS if the 100 was anything to go by and will be a bonus if it's certified for LCY too.
(wonder if Cityjet's choice of new airframe was premature - of course, all comes down to overall costs of purchasing and operating)
