i guess you mean CRJ
As a rookie with no prior Jet experience i would choose the 737 anytime. Not that the CRJ is incredibly difficult to fly, i personally think it's fun to fly manual raw-data once you get the hang of it, but compared to the 737 it's a lot more unstable and pitch and trim sensitive... It takes more time to get used to it which is not ideal for a simulator screening. I did two screenings on the 737, passed both of them and compared to my experience from the CRJ FFS during the TR i think the 737 is way more forgiving to nervous control inputs than the CRJ ;-)
Good Luck anyway!!
