Depends what you've flown before Lil. I'm on the Emb145, those who came from Turboprops like its performance, altitude, speed etc. Those from heavier types notice its light and unstable nature more, and that its a bit slower than other jets eg A320, B757.
To operate on the line it's fine, serviceability is good with my company. Seat can get a bit uncomfy on a 3 hour leg, and the only toilet is at the back meaning walking through the cabin during the flight.
It is a challenge in gusty winds and crosswinds, slightly more than other A/C, due to it being light and fairly unstable in speed, especially landing at light weights. But I handfly it alot and it is good to fly, maybe a bit heavy in aileron.
Any specific questions do ask. Best of luck with your course.
