No wing walkers required for a saab, unless the markings cannot be seen on the pavement. So... its quicker and easier to park a saab than it is to park a CRJ. It's not a 9E vs. XJ thing.
9E vs. XJ outstations... ever been to MLI? LNK? Everytime we go, there's a new bass ackwards procedure. There are also horrible XJ out stations. The worst ones however are the outsourced outsourced ones like WFS. This isn't a ****ing match between the two companies. Mine isn't better than yours. There are some horrible mainline stations too.
