I've been fortunate enough to fly on most things out there, including the Aeroflot Superjet 3 times, and i can honestly say hands down it beats pretty much anything else out there in the same size. It is very quiet, comfortable and i'm told it is very efficient. It combines good strong Russian airframe design with Western tech. I can't wait to try it out with Cityjet. The only real competitor to it will be the CS-100..
