It looks nothing at all like the older CRJs, although the screen size is similiar with the 900s. Not sure about the RJ autopilot but the Qs is junk. You can give it a 5 degree intercept and it will still fly through the loc and will not lock on to it until the FAF. It is also not three axis so you are kicking rudders all day.
As far as automation, again I do not know much about the CRJs but I would say it may be better. It does all the usual except has no autothrottles. Your question is a little vague though, what specifically are you looking for?
(I have no idea why this RJ photo wont show up. Here is the link anyway)
