FTD and SV,
The original 146 certainly lacked some of the toys. However, the RJ series has all the modern gadgets like EFIS, FADEC, EGPWS, autothrottles, Cat3B autoland, etc. In addition, it also has a more 'user-friendly' autopilot Mode Contol Panel (MCP) and Thrust Rating Panel (TRP).
I enjoyed flying the RJ - just a shame it didn't have a bit more thrust.
