The CRJ is an old aircraft, released a few years ago. Until the release of the 777, it held the title of "most realistic" airliner. The eyecandy and visuals are pretty much the same, except the CRJ might be a bit better. Systems are extremely well simulated in the 777, with an awesome FMS. Both CDU's are made by Phillip Munzel, who is an amazingly talented programmer. I would wait for the 757, because it is the best of both worlds. Textures are not cartoony, they are by Kamsin, the avionics are just as realistic, and it is a new HQ airliner to the XP community.
