The 1900D is ugly as **** but is easy and fun to fly, It's just a big king air.

The CRJ 700 is the best all around regional aircraft. Fast, with great climb performance.

EMB-145 looks cool and sleek and is an easy first jet, but it is loud and slow compared to the CRJ. The ERJ is better for the pax though due to the single A seat config. The CRJs are all uncomfortable for pax, except for First class passengers.
