As far as being more advanced, yes, the ERJ has a few more buttons than the CRJ to push. It has a radar that can map the terrain below, the plane is very smart and it makes it very easy for a low time guy to fly it, it even has a mouse the pilots can use to select points on the navigation display. The ERJ does have better performance than the CRJ but oddly it only has a cervice ceiling of 37k. Don't know what is more appealing flying a CRJ, it must be the traditional style yoke.
