Flew this with Air Koryo in September 2015 and was very pleasantly surprised. Spacious, quiet and comfortable. (I'm 1,94m tall).
From a passenger point of view I would say it stands up well to all competitors!
A great plane that can go virtually wherever you want, whether it be snow, grass,pebble or even high-altitude airports. Fuel consumption is a little disappointing considering their range. But it is a regional jet. Passenger comfort is believed to be fairly high although I've never flown on one myself. For a regional jet, the cruising speed of 840km/hour is quite good.
