If you don't like props, then you probably don't want to sly some of OA's off-peak flights to the islands. That said, I don't mind the Q400, so that isn't the reason I avoid OA.
A3 is better if you want all fan jet (instead of prop jet) equipment and also has the big plus of being in Star Alliance.
