I don't have a whole lot of Regional experience. When I compare the two that I have flown in recent time, CL and EW, I'd definitely prefer CL. They are basically like mainline but in smaller aircrafts. EW crews stink. Also currently, their aircrafts are not that nice. We'll see how things improve when they get the CRJ 900 which I like a lot (for a regional aircraft) with CL.
