The ERJ is a good plane with a lot of solid automation in the systems and a good setup in the cockpit. Despite what has been said I like the ERJ avionics better. Maybe its just prejudice, but I like the ergonomics of the cockpit with the overhead panel, the pedestal, and the rams horns. The CRJ has to cram all of the controls on the pedestal and instrument panel with a limited overhead that makes some of the controls hard to reach/use according to one CRJ pilot. Either way you choose will have a solid jet to fly. The EP's are dogs in the summer, but the LR's can usually perform well enough with a full load. I've been told that the CRJ 200 isn't a top performer in the summer heat either. The CRJ 700 is a solid jet though.
The RJ's are less forgiving with poor descent planning, in the props you can go flight idle and drop so fast you'll give some poor center controller a heart attack. Good luck with your interviews!
